Thumbtack Software Developer interview questions

Had a face-to-face interview on campus a few days after handing in my CV in the job fair. The interviewer was super nice and helpful in the interview process. Then went to an onsite. Co-founder gave a general talk for about 15 minutes, followed by 6 interviews (4 technical + 2 general + 1 lunch). Technical ones were almost the typical questions online. But I did not work well... Some of the interviewers were very nice and helpful when I struggled. But some were not nice at all. But they do care about your previous experience (projects). They did not follow the schedule strictly. In general, the interview process is very tough but I learned a lot, especially the nice culture of the company.

Submitted my resume through my campus career center. I was contacted about two weeks later by a recruiter with an interview slot on campus. When I walk in the room, the first thing my interviewer does is give me a coding problem that's described on a sheet of paper. He tells me to read it and solve it on the whiteboard. I'm surprised by this because there's usually a bit of introduction and behavioral questions at the start. I take a couple minutes to read it and jot down some notes, then start drawing some examples on the whiteboard and talk through different approaches. As I'm talking, he doesn't really look up from the computer and it doesn't really seem like he's listening. I start to get annoyed by this but I keep talking and start coding. I ended up running out of time at the end but if I had about 3 more minutes I would have finished. I get a rejection email a few days later. Overall I'm very disappointed by the process. I heard that Thumbtack was a fun place to work with a great culture, but it seems like during the interview the only thing they cared about was whether I could code and solve the problem. They didn't seem like they wanted to get to know me at all, and the interviewer was very cold during the entire process. The recruiter was very friendly though, but based on my experience during this interview Thumbtack doesn't seem like somewhere I'd want to work.
