I had an interview with an in-house recruiter. It was a very simple call about my prior experience and what I was looking for in my future career. The call was easy.

Next, I was connected to another recruiter who set up an interview with the Lead Software Engineer of the department where I hoped to be employed.

Unfortunately, it seemed like she was calling from a payphone in the middle of a desert sandstorm, and she had an incredibly thick accent, making communication very difficult from the start. The interview was quite rough. After a whole slew of misunderstandings about what she wanted, she gave up within 15 minutes and told me she would not move forward with me, even if HR forced her. Ouch. It felt unprofessional, but I suppose it was that bad.

I received a "Dear John" letter a week later, which I absolutely expected.

What is a singleton and how would you implement that in Java?

How would you reverse a linked list, and how would you implement that in C++?
