Just chill and read some hackernews or something. You will be unprepared no matter what, that’s how every job is at first.

Just curious— is this FTE?

I see it as a sort of red flag that start date is a few months away.

I’ve managed to snag a job which is great, but I also have no experience.  If I have a start date that’s a few months away, what should I do to prepare in the meantime? Has anyone else been in the same boat of being ok at Leetcode, but dramatically unqualified for the actual job?
