I applied through university. I interviewed at Opera Solutions in Sept 2017
Interview
The interview process includes written test (quants, english and general knowledge) followed by a series of interviews (the first round of interview mainly consists of solving puzzles, the second round of interview was a panel interview and the third round of interview was the HR interview). I cleared the written test but couldn't make it through the first round of the interview. The preplacement talk was interactive and the interviewers were helpful.
Q: Asked many puzzles such as you are given 9 balls of identical shape and size but exactly one of the ball weigh more than others and you have a weighing pan which you can use only twice .. then how you will extract the heaviest ball out of the nine given balls ?
