I do have around 2 years of experience in Modern Android app development; Watching this video for the first time, about a year ago, I was scared. This is the third time I'm watching this video; And I can answers 70% of the questions asked.
I have published 3 apps, with an average of 10 users :)
At the Turing website, I have failed the coding challenge like 3 times; And in every latest attempt, I have a plan on how to solve the problem, without opening any window or tab, just honest self assessment. I'll keep on improving on my Android skills, improve on my problem solving. I do believe that I will be a Turing developer soon.
Add questions regarding Dagger2 and android architecture components like viewmodel,viewmodel factory,databinding etc. Also add question on MVVM architecture.
This are very basic questions for android. Questions on Kotlin are expected on advanced concepts like - Room, security hardening, ViewModel, Coroutines, Jetpack architecture components, Scope functions, Dependency injection, Generics etc. Also should be on streams, lambdas.
Thank you for your feedback!

Even intellij had Their cons divided into 2017 (kotlin jumpstart) 2018, 2019
Highlighting android's jetpack
For docs
It's just beter to just read the whole Google docs plus intellij's Kotlin docs for more Kotlin fun
AIDL description is not the best you can give.
It’s a tool that allows you to define programming interfaces for interprocess communication (IPC) on Android devices.
IPC is a mechanism that allows processes to communicate with each other and synchronize their actions.
Hey, thanks for the video! I like that the production quality is good, the atmosphere is friendly so it's pleasant to watch.
However, these are not really the questions a Senior Android Dev would get as-is. The thing about seniority as to how it's perceived by a lot of companies - the more experienced you are, the deeper you should know the technical side of things. And, to the best of my knowledge and experience, this is what the interviewer tries to check. For example, the real question could start with "What do you know about the AIDL?", but then there would be a cascade of deep and tricky questions into the topic, like "How does AIDL work under the hood?", "What are main risks of AIDL in a case of receiving a continuous data flow?" and much harder ones.
Overall, questions in the video barely scratch the surface. If we take them as-is, they really are suitable only for junior dev interview. Writing this as an improve sort of feedback to the channel, and to warn potential middle devs willing to try for higher positions.
Thank you for your feedback!
We'll make note of this and be sure to include this in our future videos.

Can't agree more. Came in the comment section to share the same feedback. Thanks!
I am Android dev in final year, looking for jobs .
Thanks it's very informative
ANR - Application Not Responding - it occurs when we are performing large ops in main thread and UI want to perfrom some action but main thread is busy in doing other jobs so ANR occurs
Thank you for both...
Hi jose! Its very informative video and it will be great it you share code questions for android developers. Thanks!
Hi Irtiqa, we'll definitely do that! Thank you for your comment, be safe!
boot completed does not notify in all device because of custom android ui by brand ,realme ,redmi etc,how can we achive that
Thanks for the video.

I am a flutter developer and passed the test even also. And now I am preparing for the coding challenge. But can you tell me why there is no DART🎯 language available for coding challenge ?
Hi 😃
Please write to us at support@turing.com
Our team will help you out on priority!

Hye jose, its pleasent to know all these things in a professional manner. I have an other question just to enhance my knowledge. Here it as, why all of these questions are asked to a developer having experience of 4-5 years as you asked to Akeel having experience of 10 years. How could we differ the experience terminology in the sense of these questions.
Hey! 😄
Great question. So, the discussion to assess the work experience & seniority happens during the technical interview round once the candidates pass the skill tests.
Hope this helps! You can also find answers to common developer questions on our FAQ page: turing.com/KrDKoE 🙌
Regards,
Turing 🚀

Well, usually at interviews you have to be sure that the interviewed person is not a fraud person. From my point of view if a person passes some Android questions then the interviewer should focus on the interviewer's portfolio and maybe on a test project which the interviewed person already solved or over a project which he can solve it in real-time.
Of course, nothing is bulletproof. However demanding some knowledge like "telling me how you will change or update the drivers into a AOSP code or how to configure the AOSP functionality for a specific case" can be useless if the company doesn't work with this or the interviewed person background didn't required to work with such specific and particular use case (This was just an example of what things should be considered).Remember today we have Internet, and GTP and BARD and more someany other options to get an answer. So I think this kind of questions are useful for a partial interview process but after that, the interviewer should go deeper more to the company use case and interviewer's background. I remember that once I got some questions related to git (some custom commands which in some companies are not used at all. Does it this mean that I had to learn the entire GIT? No, there is internet you can find in 10 minutes the answer to your question/use case and to implement it). I can talk about this entire day ... From my point of view the portfolio of the developer, his own projects, experiments are the best recommandations.
code challenge for android please
Thank you for your feedback, Asma!
We'll make note of this and be sure to include this in our future videos.

Flutter Mock Interview????????????/
Great suggestion, Sulaiman! Thank you ⭐
We'll make a note of this & include this in our future videos 🙌
Pretty much obsolete for 2023/2024.
Too much threading and now Android turned into Kotlin first, and we do not use threads anymore (not directly as we did with ugly Java) we do use Coroutines now for all of this things.
Also activities are pretty much not used anymore since compose is here, we only have MainActivity and thats all.
Another suggestion, if u make a newer one, please interview a native english speaker because its really HARD for us as NON english speakers to follow this kind of accents
Think that you sound exactly the same for Natives... stop beeing racist and work harder to understand
