I applied online. The process took 3 weeks. I interviewed at Simplex in Aug 2025
Interview
Process was very smooth, and HR was on-top of it. I had an initial call with HR, a technical phone screen with a seasoned engineer, and then a two round on-site (each with 2 employees, including the CTO). The only thing that stood out as unconventional to me is that they don't do code reviews. There's definitely pros-and-cons for this, and if it works for them, then it works. The office is lovely and is pleasant to be in.
All the technical questions asked were fair. Get ready to whiteboard and vocalize your thought process. While I didn't end up getting the offer, as I think they went with another candidate, I'd love to interview again in the future, as everyone is friendly and I felt a solid cultural-fit with the firm.

Question 1
ATOI
Allocate a 2D array on the heap.
Implement a vector randomization algorithm.
The recruiter / HR was extremely confident in her ignorance. I asked some basic questions about expectations and next steps, and she was adamant that “we don’t do any object oriented programming here, we only do C++”. I made a mistake by not correcting her, but she was so confident, I let it go. But lol, I have nothing more to say here.
Yes the interview was easy and simple behavioral questions were asked followed by a technical interview. I would strongly advise to interview at this location. I would advise against late applications.
