This question already has an answer here:
I recently interviewed at an agency for a web development internship. It went pretty well, and the interviewer said they'd call me the day after (latest by the afternoon). They said that TWICE during the interview and when I was leaving as well. But it's been two days and still, no call. Should I email and follow up? If so, what should I write in the email? It's frustrating when they make a false commitment like this to call on a specific day and not follow through. They could've at least given me some BS line like "we'll call you if we're interested" then I would've pretty much known that I didn't get it rather than having this false hope.
