So I did a second interview for a position on April 18th. It went very well and the individual said that he would get back to me no matter the decision. I hadn't heard anything and sent a follow-up/thank you email on May 5th. He immediately replied back, said he appreciated the sentiment and said that the position has kind of taken a back seat because they were major sponsors of a big event in town and he would get in touch with me as soon as the event finished which was May 13th. Well it has been two weeks and I haven't heard anything from them yet and as far as I know the position is still open. Do I send another email or just wait?
