Pretty Professional and smooth interview process.
Had a initial recruiter phone call and after that was scheduled to speak to one of the Senior engineers over on their team.
The interview was difficult. There were 2 questions asked in the interview on coderpad.
1.) A small android challenge. Some basic questions about Android and then a deep-dive into a specific topic. Over here looks like the interviewer was looking for a specific answer and i was finding it hard to gauge what he was exactly looking for, in the end he gave me the hint and then i answered.
2.) Coding question. This was a difficult problem to solve. Think about leetcode hard. And he was very specific about what he wanted.
The question was to implement a LRU cache but for the backing data structure only an ArrayList can be used. It is solvable if there is another data structure like a hashmap which you can use or obviously a queue(which kinda beats the point) but a single arraylist was tricky to implement in 25-30 mins and that too a working solution which passes the test cases the interviewer had got with him.

Question 1
Implement LRU cache but the backing data structure is an Arraylist
First I got contacted by a recruiter which asked about my experience and 5 simple android questions. Then I had a phone interview for one hour which is to create an app and add features. The last round is a six hours interview, first is a design-architecture interview, then you have to develop an app for 2.5 hours, then 2 engineers look through you code and ask questions about it. Finally there is an interview with a Engineering Manager. I did well on all the interviews and passed them all but design-architecture (with minimum feedback) and got rejected. The developer didn't look really experienced but I assumed he had knowledge of many things which probably led him not to understand all my ideas. So one advice is to explain everything from the beginning like to a Jr dev.
