Interview Process

  • 8/12: Sent out the internal recommendation letter.
  • 9/21: Received round 1 technical interview invitation.
  • 9/25: Round 1 technical interview. The first part focused on my experience in SDET, behavioral questions, designing an automation framework, and test scenario design (given a feature, what would you test?). In the second part, I was given a LeetCode easy question.
  • 10/1: Received round 2 technical interview invitation.
  • 10/8: Round 2 technical interview lasted about 45 minutes. The first part was again about my SDET experience with more technical questions and test scenario questions. The second half involved an application question (non-LeetCode). I discussed my ideas after coding a bit, but the interviewer indicated that time was up after only 15 minutes.
  • 10/14: Received rejection letter.

Technical Questions

  • LeetCode Easy Question: Two Sum

Tips & Insights

The overall interview was conducted in English and felt comfortable. However, the second round included questions that were quite deep, involving tools I had not worked with before. I felt that I struggled in the first half of the second round. It’s crucial to prepare thoroughly for each opportunity, especially given the current job market challenges.
