Had three interviews that were wildly unaligned and despite being offered a position in one of them, never heard back (note- I reached out to no avail). Clearly the company was expanding too fast to handle growth.

I had a screening interview with a recruiter. It went well, and I was move on to an interview with a project manager. She showed interest, and asked me to do a writing task that took approximately five hours to complete. She thanked me for the submission via email and then vanished. I was completely ghosted! What a waste of my time, and so disrespectful! (The interview was a simple process, but the writing task was very time consuming if they are not serious about the applicant. Every applicant who submits a writing project deserves some follow-up and/or feedback.)
