ZapLabs Java Developer Interview Questions
& Process

First, there was a phone screening with some basic Java questions. Then, I had a video call with one of their engineers. They asked me a Java programming question that was pretty easy. The onsite interviews were more focused on algorithms. You really need to practice a lot of Java algo questions to get through this.

The interview process was pretty standard. First, there was a Skype interview where I was asked two coding questions. Then, I had an onsite interview with nine people. Most of the interviewers were friendly, but one was very rude and unprofessional. She gave me a linked list problem to solve on a whiteboard. After a few minutes, she started talking to her colleague, which was very disturbing. She didn't understand the code and wouldn't let me explain. At the end, when she asked if I had any questions, I asked about new products, and she responded rudely, implying it was a strange question and that I had no respect for the company.

I first spoke with someone at a career fair, and then they asked me to do a video call interview with an Engineer about a week later. The video call went pretty well. After that, I was asked to come in for an onsite interview and was given directions to the building. They didn't seem very prepared for my interview though, as the room they set up for me was being used by another group. I was interviewed by two engineers and asked some Java questions and about 2-3 algorithm questions. I didn't get an offer in the end, but it was a pretty good experience overall.
