4 rounds. First was a screening phone call for about 15-20 minutes. Second, was a coding assessment with a 4 hour time limit. Next, was a technical phone interview. This was where I failed.

Began with 30 minute phone calls with a recruiter and engineer each. Then I had to do a 4 hour coding assessment. After this I was asked to prepare a PowerPoint presentation for a 45 minute session of presenting and questions. The panel I presented to was extremely rude. One did not look up from his phone and others were constantly on their laptops doing work. Multiple questions asked on details covered previously. Two hours later one of the engineers told me I wasn't a good fit, gave a few buzz words and escorted me out.
