Last year, as a freshman, I had two interviews. I met a representative at my college's career fair, and they signed me up for an interview slot the very next day.

The first interview was straightforward and technical, although one of the two interviewers spent half the time on his phone and the other half trying to intimidate me. Nothing too tricky, just some data structure questions and some optimization problems. They were pretty good about talking you through the problems.

I got a second interview later that day and met with two different representatives, one of whom I had initially met at the fair. It was half technical and half behavioral. He was a real nice guy (I'll call him S). I ended up not getting the offer, but as a freshman undergrad with a subpar GPA, this was totally understandable.

This year (as a sophomore), I applied online in the fall semester and was rejected immediately. Luckily, at the job fair in the spring, the same recruiter, who I'm calling S, from last year was there. I told him about my situation, and he got me through to HR to set up an interview.

So, the first interview was with him again, and it went fantastic. Pretty straightforward, with lots of string manipulation and memory management stuff.

The second round, later that week, I was sleep-deprived, and the questions were harder. Lots of memory management stuff this time, including a series of questions on linked lists. It didn't go so well.

I haven't heard back since then, and it's been a month. I've contacted S and another HR representative, to no avail. Pretty frustrating.

Linked list memory management: deleting a node from the middle of a list was easy.

Next question: how to delete a node from the end of a list?

It was too tired to think and realize this was a trick question.
