There were five stages in the interview. The first round was the aptitude(general and technical) and from this, people were shortlisted. This was followed by two programming rounds. Each had a time duration of 45 minutes before which the problem statement is to be completed.

After that, there was a one on one technical interview with questions from the basics of your subject (not just on the area of interest) and DBMS queries. The interviewer helped to arrive at the answers correctly. The final round was the general HR. Some of the shortlisted people had another programming round and a technical HR in addition to this process.

I was finding a path from one end of a matrix to the other and finding all the combinations of words in a sentence.
