I think they need to ramp up their interviewing process drastically.

I was hunted by a recruiter on LinkedIn and scheduled a call, but I didn't receive one. I had to reach out to them to ask if they had missed the schedule, which apparently they had. After rescheduling, we finally had the screening call, which was only about 5 minutes long.

Anyway, I made it past the first round. One of the questions was quite challenging; it was something called the "Partition Problem." I solved the first question in about 5 minutes, and then the recruiter threw another question at me.

Here's the catch: these recruiters seem to be pretty clueless. As soon as they presented the second question, I recognized it as the "Partition Problem," which is NP-Hard and was famously solved by the mathematician Ramanujan. I told them, but the individual hadn't heard of the "Partition Problem" or "Ramanujan." I was stunned.

Regardless, the only way to solve that problem is if you knew the question beforehand and used a DP approach, which of course, I couldn't, and I was out.

The shameful part is that I had to follow up with the recruiter for about a month to get feedback.
