I had a lot of difficulty scheduling the interviews. The whole process lasted for about two months.

First, I had the interview with HR, where they talked me through the hiring process. It consists of five interviews:

• 1 HR
• 3 technical
• 1 manager

I passed the first of the three technical interviews. The first one was easy. It consisted of a simple coding task (write a well-formatted multiplication table for a two-number input) and some questions about data structures and SQL. I managed to get everything done before the end of the interview.

After two weeks, I had the second technical interview. It was an easy LeetCode problem (Best Time to Buy and Sell Stock). I struggled with the optimal solution but eventually solved it with a hint from the interviewer. The other task was finding errors in JavaScript code. In the end, I didn't pass because I needed a hint on the first task, I missed a typo when debugging the JavaScript code, and I was too slow, even though the interviewer confirmed everything was fine at the time and I finished before the end. I should have checked better.
