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.

Coding interview: LC Medium Similar to the following problem: "Given Employee-Manager pair in HashMap and a manager, print all employees managed by the given manager." System Design Interview: A non-distributed API design problem involving designing a chess API Second Coding Interview: Given Go code on an IDE, implement functionality, or fix a bug. Easier than the first one. Just know your Go. I highly recommend you do not interview with OkCupid. The company is toxic and is about to go out of business. The company is an afterthought in Match Group announcements.
