I received a test with three days to solve it. The test consisted of two problems, which I solved.
A few days later, the recruiter contacted me to thank me for my time but stated they wouldn't be moving forward with my application.
When I asked for additional feedback, I was told that my implementations didn't pass the hidden tests. However, when I inquired further about feedback, they cited company policy as the reason for not sharing specific details.
Oddly, I tested one of my implementations on LeetCode for the same problem and passed all 100 tests.
Overall, it was a very bad experience, and I wouldn't recommend wasting any time with them.
