Had a Webx session with Technical Leader. Got through the first round. Then had a second round of Webx interview with an engineer which also went well. The third round was a coding exercise in Python. Was able to do this exercise even though I had no prior knowledge or experience with Python. I guess they were looking at how I would perform given a language I had no prior experience in? The recruiter went silent after the third round and did not respond to any calls or email checking on the status of my candidacy. So I assume I did not do well in the coding exercise or they were expecting a different approach to the solution.
