Classic leetcode interview. Though, was told by the recruiter it wasn't "true leetcode, it's more practical DSA stuff".
The interviewer explained the prompt incorrectly. Even after I confirmed the requirements multiple times, I got about half way through my solution before being told "Oh, sorry, I forgot to tell you X". Her suggestions towards my solution lead me further away, and she even admitted "I don't know how to solve this one either" - I got pretty close to a working solution, but didn't finish.
The interviewer showed up 10 minutes late, and did not extend my time to find a solution, she said I took too long, and ended the call right on the scheduled time.
Recruiter ghosted me for a good couple of weeks and I had to chase up multiple times to get the official rejection which had no feedback.
