Technical Behavioral
Extremely unprofessional conclusion to a demanding interview process. I participated in multiple rounds of interviews including a recruiter screen, technical screen, and super day with 4 interviews (3 technical, 1 behavioral). The interviews were difficult but fair and allowed candidates to showcase a range of skills used every day in software engineering. After my final round, I was told that I passed the interviews and received positive feedback from the team, but that they were "waiting for more headcount to open up" and we would continue with the team match process at that point. Stripe reposted the same job listing a month later, indicating that more headcount opened, and I reached out to follow up. I have now reached out multiple times over email and phone but have been completely ignored. After the time commitment for both me and the employees who interviewed me, a proper rejection is the least Stripe could do. The conclusion of this interview process has been completely unprofessional.

Behavioral Coding
First, there was an HR screening. The interviewer was great, she explained everything clearly and asked good questions. Second round was a pair programming session where I could use my own IDE. It was a bit hard to understand the interviewer though because he had a strong Indian accent and I couldn't understand about half of what he said.

Coding Technical System Design Behavioral
Applied online and the recruiter got back really fast, on the same day actually. The first thing was a technical coding interview. After that, I had a chat with the recruiter. Then, I was invited to a virtual onsite which had 5 separate interview rounds. It took about 5 hours in total. They said I could split the onsite over two days, but I just did it all in one go. I didn't get an offer in the end, but it was a good experience. The recruiter was super responsive from the start and all through the process. They even offered a quick feedback session after, which was nice. Honestly, one of the easiest interview processes I've been through.
Confirmed questions2 questions
- Practicing LeetCode can help with the coding challenges.
- For integration interview, you would need to make api calls, open/save file etc.
