Initial call with HR was fine. It's what one would expect from any SWE process at that point. Nothing particular to note.
Then there's a take home task. No option to avoid it. When I got the spec for it, it said that it would require about 6h of time to complete, which is IMO a pretty unreasonable amount of time to ask candidates to spend doing a take home.
The take home itself isn't too hard, but one thing that really tripped me is that they give you a fixture with some data. This fixture has a header and a footer. The take home doesn't really talk about the header and footer, and just points to some documentation about the body of the fixture. It's extremely hard to find documentation for the header and footer. I thought I'd show some attention to detail by finding the documentation for it, which took a while. At the end of the day, being good at finding and reading documentation is a big part of what it is to be a good engineer, and I do this daily at work.
In the end, I got some feedback saying that it looked like I spent too much time on the header and footer and that it wasn't required. Perhaps they should consider either removing the header and footer or telling candidates that they shouldn't focus on that, lest they waste time with it.
I'd personally avoid interviewing here, just from the take-home assignment I can see that the engineering culture is not great.
