I was contacted by a hiring manager after submitting my email during a campus career fair. I sent my application and was soon asked by the hiring manager if I was available for a remote technical interview. We agreed on a time for later in the week.

When that time came, I waited 15 minutes after I should have received a call before I contacted the hiring manager, asking whether the interview was still on. The hiring manager tried to say that we had agreed on a different time all along, despite our very clear email trail confirming and re-confirming our set time. Luckily, I was available for the time that she claimed we were set for, but it left a very bad impression of unprofessional handling of the situation and disregard for my time (she didn't apologize for her obvious mistake).

Finally, during the actual interview, I was paired with a current software development employee. We had a conversation portion in which we discussed my interests/experiences, etc. Then, we moved to a technical phone portion where I was asked about various sorting algorithms and runtimes, and then onto a Google Doc-esque environment where I was asked to implement mergesort.

The phone interviewer seemed very pleased with me and suggested I would be moving forward, but I never heard from them again.
