External recruiter put my profile in their radar. Internal recruiter called me, he was very positive and encouraging and fun. Then, a take home exercise is given. It's in C++, and you need to Google around to arrive at the best solution (it's parsing words and sentences). It takes 8-10hrs and it is unpaid. Then an onsite interview with CTO, manager, staff engineer and then half hour lunch with the team. CTO asks technical questions. Staff engineer asks the design question - you need to design a user facing application with low latency and high traffic. Manager does pair programming where you need to build and endpoint and debug existing code. Overall the interview is very technical and less on the culture fit - which to me is a big red flag. Based on their answers to my questions, it seems like they're a very small team with large load of work, and their challenges are non-engineering and mostly on the business side. They appear to be Tinder-lite and the afterthought within the Match Group ecosystem.
