Varo Bank Software Engineer interview questions

Had a call with recruiter, was given a take-home challenge. Here is where it gets weird. The take home challenge is not clear in the instructions. You're told to complete it in three hours the moment you take a look at it, but there was a lot of issues. The interviewer on-site told me they sent it out with a lot of issues on accident but decided not to notify me, but apologized on-site. The on-site was fine but two of the 5 interviewers weren't that communicative. One had a short temper and wanted to leave early. It was difficult to understand his thick accent.
