WEX Lead Software Engineer interview questions

I met with a third-party recruiter who was recruiting for WEX. I was told that the first step in the process was a take-home assignment. I got sent the take home assignment, and it was excessive. I was expected to get this done in 5 days, so it was my personal time without being paid. The requirements were to make sure the API was "production-ready." So, if you make it past that point, then you would have 3 more interviews over the next 2 weeks. The first would be a live-coding interview, which previous people have said are medium leet-code questions. Then another technical interview, but more conversational, and finally a third interview after that. So, these last 3 interviews would be over a 2 week span.
