Is it really a fresher interview? this guy is answering all the questions like a pro.
I presume this is some mock interview rather than a real one. The level of questions are fresher based though, but the guy seems to be 1+ year experienced.
These are mock interviews, IBM does take these types of interviews
I love how confident and knowledgeable you are. Just beginning my journey into web dev here in Egypt and stumbled upon your channel. Wish you the best of luck and a fitting opportunity worth all your effort.
Hats Off to you brother, The way you handle your problems while countering an error required an immense amount of confidence. Good Luck Man.
Thanks bro
I guess its experience.
The quality of your answers reflects the understanding you got.
Superb answers, moreover by hearing ur answers I can actually learned a lot of things
The perfect podcast for software developers 💯
Interviewer - Diffrentiate useMemo and useContext (Time Stamp - 6:00)
Candidate- Told her about useMemo and useCallback
@RakeshKumar-zc6gg Really, but his confidence made it to a very convenient move.
yes bro i also think that what is he saying 🤣🤣
I think, She was about to ask useCallback but mistakenly said useContext() 😁
Brother must have memories interview questions,
THIS TUTORIAL REALLY WORKS I AM FROM PHILIPPINES! THIS MAN DESERVES A SUBSCRIPTION!
Thanks
Brother, at 5:57 she asked differentiate between useMemo and useContext not useCallback
A very interesting interview indeed. I love it 😍
Glad, you liked it 😊
U r superb bro,
forEach just loops over array, it won't effect original array until unless u intentionally made change, that u did in ur code arr[i]=val*2
Absolutely correct 💯
Really hats off to you man the way you encounter all the questions is just beyond awesome really it's not an easy when you faced error part while answering !
🤘🤘
Thanks bro!
I was always scared of this video, but now I have watched it. I am learned a lot.
Awesome
forEach does not technically mutates the array, the callback function which he created does it with the index value. May be it can be used to mutate the array.
nice interview round, All answer are clear and understandable
Thanks!
Bhaii! This was super helpful. Subscribed. ❤️
Glad to hear 👍
dude what a smooth interview. good job!!
Glad you enjoyed it!
i subscribed this channel just because of that guy who was in interview hats off bro .
Thanks 👍
bhai nice vedio bahut kuch sikha for interview thanks keep it up
Thanks 👍
One suggestion... {isError ? ERR_MSG : null} can be cleaner with {isError && ERR_MSG}. Fits on 1 line with linters :)
Absolutely. Thanks 👍
Be careful when you do this with array.length && , it will render a '0' if length is indeed 0. You should always do array.length !== 0
Local storage and session storage both can store up-to 5 mb and it is limited.
I guess local storage can store 10 MB and session 5 MB.
Not sure. Will check and revert.
Local storage 10mb session storage 5mb
Thank you for sharing!🙇
Thanks 👍
Just for people watching this !!
Both forEach and map -- does not mutate the original array.
But the callback function in both of them can. (So not a difference)
Great content!! Keep it up!
Agree.
but one returns a new array, while the other returns none. so their is difference
I like the way you answered a bad question: useMemo vs useContext and you answered useMemo vs useCallback
1:11 yes it just reranders every spot it found the most basic difference like prop change or state change even if nothing in the UI changes because of it making it have extremely high rerander amount that’s not a reason for react to be popular it’s just an explanation to how half of all frameworks does it
Hi, thanks for finding out the gap in answer.
Popularity comes when you have something which makes you stand out from the rest.
React has V-DOM which is its one of the biggest selling points. which makes it popular.
React js is a shame and blasphemy to JavaScript community. Governments should ban the use of this stupid library. Same functionalities can be achieved with Angular and Svelte with less frustration, so what's the point of using the stupid react js which makes web development unnecessarily complicated.? Those who use react are slaves.
good job, keep it up
Unbelievable!!!!....This much of confidence bro, if i were the interviewer I would be highly impressed by the answers you gave. BTW how did you prepared for the interview bro and from where do you refer.
Thanks bro.
I'm assuming you are a fresher. Watch these videos

@@itscodingdoctor Thankyou soo much bhai
Welcome 😊
i feel good because i know answers to almost all the queations
Awesome
Bro error handling achi hai apki....sometime there was time I panicked and ruin whole interview. Great resources..Good luck
All the best
Mind Blowing. You are Hired Brother !! :)
Yup!
Nicely done bro...
But it seems to me interviewer focused more on theoretical knowledge than practical. Because it seems she was straight forward reading questions form somewhere 🤣🤣
I know, it's a fresher interview!
the interviewer asked for difference between usecontext and usememo but he said the difference between useMemo and useCallback
True😅
Ty pal for this
👍
I think last question is good.
U will be manage a better way.
Gud job bro
1st question asked to me in my yesterday 20 july in technical round.
Great 👍👍. Please try to add some questions from your interview in the comments. It would help others!!
@@itscodingdoctor Didn't you have the technical coding round like apart from this round? Or was it just one round that happened?
@sanju Kumar would you like to answer this question ❓
This was the only technical round i had. After this there was HR/Managerial round
@@itscodingdoctor How much exp was this interview for?
We want more interview video like this for react
Here you go brother

@@itscodingdoctor I am visiting all these videos bro...is it for experienced react developer?
This interview is for freshers only. But, other interview experiences in the playlist are mixed (fresher and experienced). Go through all the video to be on the safer side.
When you attend any interview, let me know how many questions were asked from you from these videos.
For fragments we can add it does not create extra node
Correct
You can show error by using text.length> some number display error
Nice video. So helpful
Thanks bro 😊
Thanks bro that was really helpful
Thanks

What do you think after going through this interview. Do you feel like the same questions are being asked for both entry level and experienced level?
Some questions would be same no matter you are fresher or experienced.
I don't think it is for fresher. It is atleast for 1yrs+ experienced.
Actually the difference between map and forEach is that map returns a new array and forEach just loop through the array and let us perform what we want.
In Map also you can mutate the array like given below.
actualArray.map((item, index, arr) => {
arr[index] = arr[index] * 2
return null;
});
Agree
Yeah that's what I meant in the video. I just wanted to show that forEach is used to loop through the elements and perform any operation of our choice.
4:30 state is immutable, that is why setter is used :/
Which position and also where you got to know about open position ??
As I guess direct request for referral can't be the case ??
For the position of entry level react developer.
06:10 The question was to differentiate between useMemo and useContext but the candidate has explained useMemo and useCallback. How he is selected in IBM?
If IBM is asking these questions then trust me it’s to beginner, can you tell how can you identify whether the browser callstack is empty or not ?
Silly question "why is React popular?" defineatly the interviewee is better than interviewer
In 6.02 : she asked differntiate between useMemo() and useContext() but he explain useMemo() and useCallback()
I guess that was slip of tongue, she actually wanted to ask useCallback(), because useMemo() and useCallback() are close friends at least during interview
Exactly
Good finding bro
Bro I am 2018 pass out and till now I was working on nontechnical organization, but now I want to work as front end dev, I have made few projects, what should I do? I was not that well on academics, and that big gap, that's why I am not getting selected.
Masai school search it
@vishal Gupta how much experience do you have?
Start with an internship that offers a full-time job after completion and get some experience from there.
Is this a probable interview for 2 yrs exp developer? or it will be much harder than this ?
Is there any opportunity for internship in your company?If yes how to apply for it?Plz guide
can you please elaborate on how did you apply for the job and what are your qualifications?
You can find IBM employees on LinkedIn and ask them to refer you.
Try to ask many employees, may be one good person will refer you!!
@@itscodingdoctor But thats not an option for freshers right, I assume you have atleast 4-5 years experience
The 2nd difference between map and forEach has a small error. If we write map in the same format you did for forEach, it will mutate the original array as well.
Come for the thumbnail, stay for the answers.
Hahaha! Good one 👍
The type of questions suggests that the interviewer herself needed to be interviewed
It's a fresher interview bro
Bro the interview questions were not easy for any fresher to crack, and the coding questions were very easy and according to fresher level.
That's fine. Prepare well before sitting in an interview. You can answer question these easily.
Great video series bro...Just want to know whether they ask DSA questions in coding rounds for React Position. If yes then what is the level of those questions?
Thanks!
No DSA questions bro.
setError(Number(e.target.value ) < 18);
As a fresher , company hired react developer ?? because I am 2023 batch and IBM does not give proper description as react developer or else, they just hire to ask simple dsa questions??? as a fresher how can I apply for react developer in IBM
No DSA asked.
Try to find references on Linkedin. And also apply on company/job portals.
Thanks bro please upload more
I will try my best
Bro i am fresher I have good knowledge js and react.. Can i get select by ibm even 2 + years experience role
Idk why they make HR people to take the interviews as opposed to a senior engineer. For a company like IBM this is bad standard.
The interviewer seemed like she didn't have much idea on what she was asking..
🤔
@@itscodingdoctor Seemed like she didn't know what she was asking. I mean you might have felt that too didn't you?
ForEach doesn't change array but you did
Good finding bro!
Btw, i was just trying to show the main difference between forEach and Map which is return...
Also, to double every element of array with forEach either you have to mutate the array or create a empty array and then push doubled values.
Interviewer is also fresher in her job. So simple questions asked
God knows 😅
Hey Brother! Nice Interview!
BTW! What was the exp level for this interview and also what CTC range they offer on this?
Thanks 👍
Experience level:- Fresher
What is your year of experience
angular also dont render fullpage
Thanks for mentioning
OMG !!
👍
difference between use memo and context??? lol lol, the interviewer is crazy🤣
Iam still waiting for that thumbnail girl in the video
She asked the difference between useMemo and useContext and he answered about useCallbacks
yes
@@itscodingdoctor both are quite similar usememo can be used for single values where as usecallback can be used to return functions and both are helpful in improving performance… idk why interviewer asked diff btw useMemo and useContext
Yes
Great content. I know that you applied as a fresher. But I really want to know how much experience you have in React. ?
5+
@@itscodingdoctor 🤣🤣 so this is not a fresher level interview naa..
Are they really asking folder structure?
What was the package offered to React Js Fresher in IBM?
It depends on multiple things bhai
i answerd all the questions
I was wondering why it is not recommended to pass data from child to parent. How can we create reusable components without passing data from child to parent?
Valid point.
the context of the questions was different, in general it's not recommended. but depending on the use case we can pass the data from child to parent.
can you please put program on adding two numbers and store that value in total using useState hook
Sure, could you elaborate the question?
@@itscodingdoctor addition of two numbers using useState hook
@@vasavijuvvigunta1867
const [addition, setAddition] = useState(0);
function addNumber(number1, number2){
setAddition(number1 + number2)
}
Jsx wont allow to return multiple html elements but why he is saying children
Bro, You wrote your age 27 when implementing "this" keyword example. Just wanted to make sure, are you really applying for fresher position?
Hahhah! My age in not 27. It was just a random number came to my mind.
@@itscodingdoctor I thought you must be applying for 3-4 years of experience, cuz you mentioned 2 YOE in accentures video.
Just had my hopes high lol, If it really was for 3-4 yoe. I'll be a able to answer some fresher questions in interview for sure XD
Thanks for the video & reply btw.
😅😅
This interview is for freshers only.
@@itscodingdoctor 😳
After listening 1st question answering 😂 i can say he is fresher
tf kinda question is "why is react so popular ", that's the dumbest question ever , lol
I know bro 😂
Believe me, this question is asked in a lots of interviews.
I suggest you don't open the captions.
Whats was the level of experience for this job ?
Brother how many rounds are there for 2 yrs experience guy ?
Any idea ?
Most probably, two technical rounds bro!
Literally nothing in his answer says why react is popular can anyone actually answer it without going into circular reasoning that it’s popular so many places work with it and that creates job opportunities for react developers making it popular?
Hi, thanks for finding out the gap in answer.
Features of react makes it popular. That's why in answer features are mentioned.
In case you feel answer could be better, please add in the comments. It might help others as well.
One of the main reasons why react is so popular is the react's ecosystem. You have so many options to choose from to your convenience for any use case be it managing large and complex forms, state management libraries or UI frameworks etc.
Thanks @rishi ks Correct 💯
Good.But it seems the interviewer asking questions from given script
One of the question says - d/f between state and props?
You have said - state is mutuable..
How that can be possible?
Yes, State is mutable. State is initialized with some value and based on user action it gets updated via setstate.
For example:- In a basic number counter app, initially counter value is 0 but on click of add it becomes 1. That's mutation.
@@itscodingdoctor that the mutation? 🤔
Eg - let name = "Dactor"
name[1] = "o".
console.log(name) // Doctor
Is not what mutation in js called?
(To update the part of something)
@@RishabhJain-qi1ms you call that mutation?? that's called immutability of strings. And yes State are are mutable data , props are those data which are sent as a key value pair from root.render(); function , props are read only data. Where as states are immutable data. you can use your props data and conver it to a state data to make it mutable
It seems like an interview of an experience developer, not at fresher level.... As the level of questions, are high
This is for freshers. In case you are interested in questions for experienced you can checkout MNC interview questions playlist on this channel.
she ask diff b/w usememo and usecontext bro give diff b/w usememo ans usecallback
W3 school examples rocks 🔥 😂
😁
Example should be correct source doesn't matter
What platforma do you use for applying for the job?
LinkedIn. Keep sending your resume to employees. Someone would refer
Bro how much Lpa should expect as a fresher (react developer) ?
It totally depends bro on many things (Your college, Skills, Salary Negotiation Skills and Luck as well) but in general for any average college students 2.8LPA to 4.2LPA
@@itscodingdoctor why it is so low
@@Viralvlogvideos I wish i could answer that.
@@itscodingdoctor dude 2.8 😂
@@itscodingdoctor watch men gets better pay
Can experience person of 1 yr will except such type of questions?
Of course, for more questions watch

Moreover, I would like to know if there are any internship opportunities available as a Js/ReactJs Developer. I checked the website but there are not any reference of that.
There should be a lot of opportunities. Check Naukari.com and LinkedIn
This guy knows how to waste time in an interview so that the interviewer cannot ask all the questions and he can achieve full marks
Anyways, that is also a skill 😀
Is it good or bad in your opinion brother?
@@itscodingdoctor both, because let's say some other person answered every question just like this interviewee and he/she didn't waste time, then if there is any situation that the interviewer has to select any one of the 2, then interviewer will select the other guy who answered it short
Where did you learn ReactJS? How much time should I put into reach a satisfactory level?
To reach a satisfactory level, keep building react projects, and prepare interview questions.
@@itscodingdoctor Thank you brother. Means a lot😊😊😊😊

@@Almighty_Flat_Earth Unnecessary complicated? Dude did you use Angular at all or you just watched some idiot on youtube and just coiped someone else's opinion? Angular is 100 times harder to understand and amount of boilerplates you need to write to achive anything is enormous. You are the only slave here if you still using that crap and writing all day long until the sunset to get simple 'Hello world' out.
Hum don't you have to parse the e.target.value as number before comparison? 🤔
No, it happens automatically due to type conversion
"10" < 18 // true
The guy answering is easily a 4+ year experienced person in React. This is not fresher
