Was sent an email with an assessment link that was to be completed at the end of the week, as they were starting the next phase of the interview after that. The assessment was mostly a cognitive test, with some basic runtime analysis in there too. I didn't hear back, so thought that was that, I didn't move on. But then a month from the first email, I got another email with a link that said to finish by January 1st, as they were moving on to the next phase after that. Upon clicking the link, I realize it's the exact same test as earlier. I did it anyway. Again I didn't hear back for a week after the first, so thought that was that. Then on Jan 13th, I got an email saying I had been selected for a video interview and to send my availability over the next couple weeks, so I sent a response that same day. That was a Friday. On Monday, I was emailed saying "Last week we sent you an e-mail regarding our summer internship position. I wanted to let you know as soon as possible that the position has now been closed." In terms of work days, I was asked to list times for an interview, and then the very next day told the position had been closed.
