Process
The process begins with a technical phone screen. This screen asks about past experience and one algorithm question.
Next, there is a take-home project with a three-hour timeframe.
Finally, there are three rounds of technical interviews during an onsite. These include two algorithm questions and one design question.
The entire process takes a few weeks.

There is a culture of firing people who have been at the company for a while. I have heard of cases of firing without a PIP in place. They are more ruthless, and a sink-or-swim culture is now in place. There are many cases of management stepping down to the IC level because of tough company expectations.
