The process was very straightforward. Had a phone screen and later they set me up with a panel of 4 for Webex interviews. The last round was with the Director, who never called. Later, the recruiter set up another call on some other day, and he did not bother to call again. This has been the worst experience I have faced. The recruiters did not have the courtesy to respond to my issues. I had to call the recruiter, and she informed that they have decided to not move forward with my candidacy. It was shocking how unprofessional these people were. And they did not even apologize for wasting my time.
