I applied online. The process took 2 weeks. I interviewed at CrowdStrike (Sunnyvale, CA) in Aug 2017
Interview
Applied online, normal application.
Phone screen with recruiter. Really short, high level, touched on resume stuff.
Phone screen with a developer. Longer, conversational and not rattling off programming trivia or obscure algorithms.
Onsite, about 4 hours long, in the Sunnyvale office. Was told ahead of time to design a fairly complex system, and given the requirements ahead of time (didn't need to bring in anything, just have my design figured out). About an hour and a half presenting the design, getting feedback, adapting the design depending on different requirements and failure situations. Then 2x 45min sessions shared-screen laptop interview with remote employees, doing data structure/algorithms live coding interviews. Wrap up with director.
Received the offer the following day.
Overall they move super fast, about 1 or 2 day turnaround each step of the way (if you're trying to line up competing offers, account for this), including from application to first screen. They seem to expect you to have done some amount of research about them and be knowledgeable before applying.
Very disorganized. Interviewers were very unprofessional, and hostile. They emailed me saying they are not moving forward with me then emailed me again the next day to schedule another call.

Interview
Was interviewed by engineers and managers from 2 different teams. The auth team and cloud engineering team. Had a few rounds with engineers from cloud engineering team and the team was very professional with their approach. The regular workout it LC based questions and queries on handling race conditions. Had another 2 rounds with the auth team one with an engineer and another was the final round with the manager. The one with the engineer was easily the worst interview i had to sit through. The engineer was dealing with some high sev issue and clearly had their hands full and was unable to concentrate on the interview. Despite me offering to reschedule if this was not a good time they went ahead with the interview which was medium level LC question that I am sure i got right. They had no comments on the code and just wanted to get of the call. The other round was with someone at higher levels from the auth team whose primary expectation seemed to be to find someone who would stretch without any questions. Should have the titled the role "Senior Slave Engineer".
On a personal level I would recommend AVOID the auth team at all costs. For the sane folks in that team my heart goes out to you. Culture within that team seems not so great.
Everything went very smoothly during the interview. After a brief introduction, we moved directly into the coding part, which was handled in a LeetCode-style format. There wasn’t much discussion beforehand, as the focus was primarily on problem-solving and implementation, making the process clear, structured, and efficient.
