* For the first round, interviewer was ok (as he's not that knowledgeble for even much in Android) He asked everything as per experience, android fundamentals & few prolem solving / app development / design related stuff * Second round was for DS where 2 3 questions asked about linked-lists; (find loop in linkedlist, different things about static in Java, reverse singly linked-list) - She was enough dumb girl as she doestn't know answers of what she asked.
