Teesta Investment interview questions

Three rounds were held . 1. First round was good as it the interviewer was fine and asked questions around DSA and OS concepts. 2. The interviewer was very friendly and supportive .He asked questions around Concurrency and designing and DSA too . 3. This was held by HR and founder of Teesta Investment . He was not much friendly and at a point was rude to talk further and just wanted to get answer to the point asking irrelevant question .
