"The last mistake that I made was forgetting to send an offer letter to a candidate. It was when I had over 40 open positions that I was managing, and I didn't find out about this mistake until the hiring manager asked if I had received a response from the candidate. After checking back on my notes, I realized that I had forgotten to track that particular candidate properly. I admitted my fault right away to the hiring manager and contacted the candidate by phone within the next ten minutes. While the candidate let me know that they were considering an offer from another employer, they ended up accepting our offer in the end. I feel fortunate that this happened early in my career because I was able to learn the importance of being organized with all candidate activity firsthand."
