I arrived at the company 15 minutes earlier. At the reception, I asked for the HR representative and she came exactly when the interview was supposed to start. She showed me around and some basic facilities. After that, she took me to a room and the rest of the interview was there. Firstly, 3 people from the team came and asked about my experience, then gave me 4 brain teasers to answer and finally asked me to implement one of the brain teasers in Java. After technical interview, I talked to the VP of the company shortly.
