Simplex Interview Questions
& Process

The recruiter/HR was super confident in what she didn't know. I tried asking basic questions about what they expect and what the next steps are, but she insisted that they don't do any object-oriented programming and only use C++. I should have corrected her, but she was so sure that I just let it slide. Lol, I got nothing else to say.

So first thing was to answer five questions on video, like, for 2 minutes each. They asked stuff like 'what makes you best candidate?', 'guess how many lights in the John Hancock Center', and 'will a third QE pass?'. Then like two weeks later, they invited 20 of us for tests and interviews. We started with a super easy 12-min language/math test. Then came a harder 90-min probability and reasoning test, with tricky questions like those from 'Heard on the Street'. They graded them fast, and in like 10-15 mins, called out 10 names. The rest of us had to leave. Then they split us into two groups of 5 for a group project. We had to pick one of three company projects to do, given pros and cons. Lastly, we had individual interviews. Each of us got interviewed twice, by two interviewers each time. Those interviews were more chill, asking about our background and why we wanted the job and to work there. The whole thing took about 4 hours, and they were really nice people.

The hiring process was really smooth with the HR team being super responsive. It started with a chat with HR, followed by a technical phone interview with an experienced engineer. Then, there were two onsite rounds, each involving two interviewers, one of whom was the CTO. A unique aspect was their lack of code reviews, which they seem to make work for them. The office environment is nice and pleasant. All the technical questions felt fair. Be prepared to use a whiteboard and clearly explain your thinking. Unfortunately, I didn't get the offer as they chose another candidate, but I would be open to interviewing again because the people were great and I felt a good cultural alignment.

The interview process began with an online Wunderlich test, followed by a webcam interview. About a week later, I was invited to an in-person interview along with approximately 20 other candidates. This involved taking a full Wunderlich test and then a more extensive test covering math, problem-solving, and basic options knowledge. Following the tests, half of the candidates were sent home, while the remaining participants engaged in a group scenario exercise, and concluded with one-on-one interviews. The entire event lasted about 4 hours. My experience was very positive, despite not receiving an offer. The office was impressive, and the staff seemed intelligent and sincere. My advice for those who reach the interview stage is to always consider what the interviewers are looking for in a candidate. While some questions seemed to invite a standard response, I chose to answer truthfully, which might have impacted the outcome.
