- Android basics, android lifecycle. - I realised that the interviewer was actually wrong about the lifecycle of a viewmodel (and I was correct) after the interview. So make sure you are 100pc confident of the answer - Got no reply from HR after following up twice , so I assumed that I was out.

- Android basics, android lifecycle. - I realised that the interviewer was actually wrong about the lifecycle of a viewmodel (and I was correct) after the interview. So make sure you are 100pc confident of the answer - Got no reply from HR after following up twice , so I assumed that I was out.

Round 1(with Tech Lead): We discussed deeply into Android Eco System. Questions were primarily about my resume. The interviewer was a really cool guy and our discussion went really well. I answered almost 99% of his answers. He was impressed and told me definitely there will be further rounds. Round 2(With A PM): it was a product thinking round. The discussion went like Think it's 2050 and the earth's temperature is increasing. How will you plan to evacuate to mars? Round 3: Design app using GitHub API to show close commit of your code repo. Use: MVVM, Kotlin, Hilt Round 4(Onsite): Told me to add the Pagination concept to the existing page along with Coroutine. Gave me 2 hours can also use Google. Same Tech Lead who was in 1st round evaluated and gave a Green Signal to HR. Round 5: Culture fitment. Normal HR Questions were discussed. Round 6: HM Round This is where things got tensed. I don't know what happened but the Hm was not in the mood for selection. He gave a cold look and started asking product questions like how much % of the notification delivery ratio was for your last product company? Why use MVVM and not MVP. Whenever I used to give the answer he was interupting in between and going to some random topic always. This kind of situation was happening almost every time when I started speaking. He was just throwing questions without listening. As an interviewer, it's your job to make the candidate feel comfortable and he did completely the opposite of that. I don't know he has some Ego issues with my current title and started making doubts about the environment and tried making me realize that I have done nothing related to Android. The icing on the cake he asked How will you design Google Doc please write all the APis, Data Structure that will be used. I tried brainstorming. But he was looking at specific Data structures in mind and told me if you won't give which DS to use then no point in discussing further. I tried my best to come up with a Data Structure to store Google Docs data. But he told me not that's not the answer. Also asked him for a hint but didn't work. Then Interview ended up abruptly. Conclusion: HMs are not very friendly and don't support you during the interview. They usually come with a mindset whether to select or not that is what I felt.
