Started off with an HR screen then had a technical phone interview that went well. I was scheduled to go on-site but then was told the company hired a new CEO who imposed a hiring freeze. HR told me that they were not hiring anymore. Then about two months later HR contacts me again asking whether I'm still interested in interviewing and what would be a good time to chat. I send my availability and am then ghosted. Very unprofessional.

Phone screen, 30 minute Google Hangout talk, 4 hour on-site, and 2 hour final on-site. Met in total with 7 interviewers, from fellow engineers to VP of engineering. The technical section wasn't too hard - every interviewer from the first onsite had one question per hour, which goes on for about 15-20 minutes. The other 40 minutes were about my background and the cultural fit. The second on-site was with more senior administrators in the company. They explained how the company runs, what they are doing and trying to do forward, and gave me time to explain why I want to work here. Before going into any interview, ask yourself - Am I a persistent, hard-working, helpful and passionate engineer? If you can answer that, you're good to go! Also, the HR is terrifically nice! :)

I started with an initial phone screen/informational call with a recruiter where we talked about the company, culture, events, and teams. Next was a 1-hour technical, video interview with an engineer. We covered 3 technical problems covering algorithms, data structures, and general programming knowledge. My interviewer was easy to talk to and offered hints as needed. We concluded with some time for questions. The third round was another video call with a director of engineering where we discussed what team I would fit on and other culture- and expectation-related details. Finally, CloudHealth flew me to Boston to do a 5-hour on-site. I met with a senior architect, a recruiter, a director of engineering, the VP of engineering, and others. We covered a couple additional technical questions, behavioral interviews, and a "real-world" programming task that I completed in the evening. I was called to offer a position the following evening. I was impressed with the flexibility with scheduling and how quick I was given an offer. I had an alternate, expiring offer and CloudHealth rescheduled my on-site and flight plans to accommodate me.
