Easy Neutral United States

I applied and a few days later got an email asking me to complete an online assessment on HackerRank. The assessment was due within a week and included a mix of multiple-choice questions plus a couple of coding questions. I remember feeling like it was straightforward, just focused on quickly seeing how I handled the basics.

About one to two weeks later, I received a rejection email. The whole thing felt short and fairly opaque—there wasn’t much back-and-forth, just the assessment and then a decision.

Average Positive Tel Aviv-Yafo

My process was pretty clean and technical from the start. After a recruiter interaction, I had a live technical screen where the conversation kicked off with a quick overview of my background, then moved right into problem-solving.

I went straight into a coding session on a shared platform and was asked to solve a medium-level LeetCode-style problem. The interviewer stayed professional and when I got to a point where my approach needed work, they offered hints—especially around how to optimize the time complexity. It felt like they were trying to help me converge rather than immediately judge me.
