The initial call with the recruiter was good! Very friendly, then they sent the study preparation guide for the technical interview.

The technical interview experience was really bad; actually, I prepared myself very well for this interview. I started providing my initial thoughts about the first approach (brute force). Then we continued talking about details until I was asked to provide a better solution. I provided a better, optimal solution, then finally, I was asked to code it.

During the interview, I provided the complexity for both algorithms (brute force and optimal one). The only question I didn't reply well was the complexity for a string comparison (constant).

But in general, I felt well with my performance, but they decided to not continue the process. It was really disappointing; no feedback. And the interviewer was rude, really bad body language and poor communication. Lack of empathy and friendly communication.
