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.
