Thumbtack Software Engineering interview questions

After applying online, a recruiter reached out to me within a month and got the process moving along. I made it to an onsite interview and my experience at the offices made me like Thumbtack even more. Unfortunately, no offer but everyone I encountered made the process enjoyable.

They first sent me the standard coding challenge for a database on hackerrank. After about a week they replied and set me up with a phone screen. I passed that one and they set me up with another one a week later. After that they wanted to invite me to an onsite but unfortunately they informed me they can't sponsor visas for interns. Very unfortunate as I was having high hopes for the company; the whole process was very well done. The interview questions were both leetcode hards or modifications of leetcode hards.
