I applied online. The process took one week.

I applied for the job on LinkedIn and received an email from a tech recruiter with a technical challenge to be completed within five days in the programming language of my choice. I did the challenge, submitted it, and after a few days, I received a reply stating that I was not chosen to move on to the next stage. They didn't give any feedback on the reason or any constructive criticism about my code. My code met all the proposed use cases, I wrote the requested automated tests, and I believe the code was simple, readable, and scalable. However, I was frustrated that I had invested hours in the challenge and didn't receive any technical feedback. I didn't reach any interview stages.
