Save some time for your self. its not worth attending interviews at Thumbtack. As many other people told about their interview experience at Thumbtack, They will not hire you until and unless you have big companies like Google, Amazon, Facebook etc. Coming to my experience, Recruiter contacted me via indeed back in October. first there was a telephonic interview where the interviewer asked me a tough question. I was able to solve it in last few mins of the interview. Then a onsite interview was scheduled which consisted for 5 rounds which include 3 coding rounds, 1 design round and 1 behavior round. All the 3 coding questions were real tough, but i was able to solve all of them with the best complexity. Even the design question was really tough and I think i did a good job there too. After 2 business days i got a call from recruiter saying that they are looking for some one with more experience than me. I really dont understand why did they interviewed me when they are looking for more experience. My experience is clearly visible from my resume. Another worst thing, one of the interviewers asked my name and which company i am working for questions. He did not even go through my resume. I was shocked when the recruiter told me that they are not giving an offer because i was able to solve all the problems which were really tough. As a matter of fact, i got a offer letter from one of the top companies the next week. I would openly admit, my performance at thumbtack was 10 times better than my performance at the other company interview which gave an offer.
