I was contacted by a recruiter for a position on the Siri Search team, based out of San Francisco. They wanted me to complete a coding challenge, which was pretty doable. This was to be followed by an onsite interview.

The recruiter gave me a couple of dates, one of which I confirmed. She never got back to me before that date. A couple of days after this date, she emailed me asking if I could make it onsite for the other date she had initially given me. I could not do the interview on that particular day because I had midterms at school.

She then said she would help schedule an interview for about a week later. She never got back to me.

Please do not waste candidates' time and energy, and give false hopes of opportunities (considering I was graduating in a couple of months). This is unfair to candidates.
