I had my final interview for a tech role nearly 3 weeks ago. Initially, the recruiter told me that he should have an update for me within the next week. That week comes by and I hear nothing so I followed up with him. He then tells me that there are delays internally due to the end of Q1 and that he should have an actual update by the following week. Again, no update by then but I decided to wait a few more days until I reach out again which was today. Told him I was approaching the final stages for another company but that my priority was their company and asked if he at least had a timeline of when they’ll finalize their decision so I could try extend this other pipeline. He responds saying he’s glad I’m still interested and that he should finally have a final decision by the coming Tuesday latest. My question is, have they been keeping me warm because I’m the backup candidate and they have a priority pick, or did I just happen to be one of the first interviewees so it’s taking longer than expected?
