Candidate interview experiences
First-hand accounts from people who interviewed at Decagon.
Software Engineer
I interviewed with Decagon.ai a few weeks ago, and overall, it was a really poor candidate experience. The questions were pretty easy but the company seems to be run by a bunch of inexperienced people who don’t really know what they’re doing. The recruiters didn’t seem to understand how to design an interview process, so they just kept adding more interviews without a clear purpose. In total, I completed eight interviews and two of them after the onsite. They kept assuring me that each one would be the last, only to schedule another. It was not only a waste of their engineers’ time but also an incredibly bad experience as a candidate. My onsite lasted over five hours, starting in the morning, and they didn’t even bother to ask if I needed food. Overall, it was not a great experience, and I wouldn't recommend it to others, unless you’re just looking to use them for interview practice.
- solve the lc skyline problem
- write code for a chatbot
Software Engineer
It was hard with JavaScript, C program and python. I passed their assessment after about 3 to 4 attempts. The staffs are very nice and welcoming. They have qualified staffs. But the only thing I don't like here is they not being able to fulfill their employment promise also their interest rate is not friendly at all
- Can you solve algorithms in JavaScript?
Software Engineer
So after we got settled in, they gave us a quick rundown of the company. Then the interview kicked off. Each of us was interviewed by two of the decagon students. The interview was split into two parts: first, a people skills part, and second, a technical interview.
