Directi Software Developer Trainee interview questions

Candidates were first shortlisted in a coding round conducted on codechef. This round was not very difficult. Then two telephonic (Skype) interviews followed in a gap of 10 days. In both interviews, I was given two algorithmic problems, first I had to discuss the solution, when the interviewer was convinced that the solution is correct, he asked me to code it on collabedit (online text editor). After these interviews, I was selected for the final round of interview. In final round, I was asked about my projects and also how would I improve their performance. The questions were a little difficult, but appropriate for the final round.
