I reached out to a recruiter directly, and was set up with a technical phone screen. The recruiter mentioned that because I had applied in the past, and had finished a coding challenge then, I wouldn't have to do it again. The phone interview was set up quickly and was pretty standard. After moving on, I was invited onsite to their HQ in San Francisco. The on-sites consisted of 1 technical interview, then a 30-minute lunch interview, and then 3 more 1-hour technical interviews. Their interviews all started with a simple "Tell me about project X" that you've done. It only takes about 10 minutes, but it's probably good to prepare answers for these. Each of the interviews were done on a laptop in a shared HackerRank. The thing with Thumbtack is that they expect your code to compile and run for all interviews. If you're not prepared for this, it can be a pretty big shock, especially if you're used to doing pseudocode on the whiteboard. I'm not a huge fan of this because you end up wasting a lot of time at the end fixing syntax and compiler errors. Remember your imports! After the interviews, my recruiter came in to check in and answer any final questions.
