I have wasted lot of money on paid courses the reason I'm saying wasted because this guy is giving that knowledge for free... Thanks
Hi Ajay ! Glad to know it is helpful.
@@SeleniumExpress and also that code popup during answer explaination is just best that way concept gets clear not just theoretically but also practically. Expecting more usefull content.
Sir more mock interviews for spring and spring boot interview questions
Couldn't agree more, I have 9 years of experience in java development but I still watch his video as a fresher.
please list down the sources where you think your money is wasted so that others would not fall for it. thanks.
Really pumped up with all the points and questions covered in this Mock interview. Spring Boot, Microservices, Basics of Hibernate, Exchange, Circuit Breaker and what not. Please do make some more mock interview videos on Advanced Java and Core Java as well.
If I had the authority, I would do 1000 likes but will do at the most shares that I can do.
Such content is never available for free, unless its "Abhilash from Selenium Express" ❤
Waiting for next parts/core java video.

You earned a follower today
Probably circuit breaker is implemented at the calling API side while ratelimiter is in-between/interrim to the caller and the service being called.
Great session. @20.22 REST API principle is not to hold state at API level. The reason is when you have scalable architecture, you have many instances of the same application. Requests are passed in Round Robin fashion so we are not very certain that request will always hit the same machine. Sticky sessions are used for sending same request to the same machine. It has nothing to do with microservices.
Loved the questions! It really felt like an actual interview
Damn
I have an upcoming interview coming this friday.
I am very knwoledgeable in React but I have been working as Full Stack engineer for 1.6 years but my java and microservices are not that strong.
I will ramp up this video today.
Thank you for all knowledge
My pleasure, Niranjan !
Sir you all videos are very informative..
Thanks for the kind words, Anish ! Glad that it's helping 🙂❤️
This video is a GEM , but would have been really really better if Krishna's voice would had been more clear..
Please take care in upcoming sessions
Hi, about 51:30, isn't bulkhead pattern better for this type of situations? I mean I tought that rate limitter is more for ddos attacks, but in this case bulkhead pattern is created for those kind of situations when one endpoint is slowing the whole microservice so others will work anyway after implementing bulkhead pattern. Of course I may be wrong so please explain why rate limitter is better in this case :). Except that, great video, I watched whole series and your videos are better than others because video quality is good, your english is easy to understand, questions are not typical, and everything is explained very well
Man , you're a legend
supredb bro
Thanks Abhilash for sharing such a Worthy content , Keep going

Great! Could you please let me know on what basis have you collected these questions for experienced Java developers?

Good Content

Hi Abhilash Can you post mock videos on core java
Amazing video, thanks.
Also, as a non-Indian watching at 2x speed, the head bobbing from side to side was very distracting 😆
Thanks Abhi
Welcome,Prakash !

Thank you Abhi
My pleasure, Santhosh.

Thank you for this video. I watched this video while preparing for Senior Java Developer Technical interview. Questions and answers are awesome. I listened to questions carefully and answered myself first. I noted every topic and researched it even more. And I learnt so many things. I was fully prepared. Then the day came. I was in interview, I answered almost all of questions, it went similar to this video. It was really good. But after a day I got a "Thanks for your interest but Unfortunately...." email.😂 I don't know man, they don't even tell the rejection reason.
keep hustle brother. you will get there.
A lot of the time, the rejections are a blessing in disguise. You’ll find the job position that’s right for you 🙏
Thanks abhi
Welcome,Prakash !
Thanks abhi❤
My pleasure ❤❤

Is "Spring boot and Microservices" required for QA SDET ?
I believe it's required. But this video might not be suitable for QA.
some very basic knowledge required if u QA to microservices. like how ms talk to each others and ms architecture.. other than that NO NEED for QA
how to make chatgpt
Play at 1.5 x
returning back the whole java stacktrace in the rest call is not the best practice...

Guys! Organize some a new mic
Little less and to the point answer could have been better i feel. It seems long time consumed for little information. In short time waste.
No knowledge in basics
