There were 2 technical phone rounds. Both interviewer were from the same team. They use collabedit for the online sharing of codes. In the first round I was given 2 coding questions. One on arrays and one on graphs. I comfortably coded first question but my second code was not up to the mark though it's logic was right. It seemed like first interview was happy with my performance. Then there was another tech phone interview with different guy who asked me a question on Arrays and strings. I gave him to solutions for the problem but he wanted the improvement. Then after 15-20 min. I got the correct solution and coded it in next 5-7 min. I feel there were couple of bugs in the code and because of the time I took to answer that question, I did not get further round of interview.
