Coding Technical Behavioral

The interview process involved a 20 min HR screen, followed by a 1 hr technical interview. After that, there was an onsite interview which I believe had 3 technical and 1 behavioral interview. For experienced engineers, the questions are typically around LeetCode mediums and easys. I did well on the CodeSignal and moved on to the first technical interview. The specific question wasn't too hard, but the engineer was quite rigid about his own preferred approach, even when I suggested a similarly efficient optimization. He seemed like the type to push his own agenda. I didn't fully grasp his pre-conceived approach when he explained it. During the Zoom call, he was audibly laughing, which made me more nervous than necessary. While the overall difficulty is reasonable compared to other interviews, the interviewer training could be better, as seeing the interviewer laugh is not helpful. There are other mentions of arrogant interviewers here, so this isn't the first time this 'culture' has been observed.

Confirmed questions1 question
  • General OOP concepts, how to optimize written methods, and understanding their complexity, though the interviewer was unreceptive to other solutions and pushed his own ideas.

Behavioral Technical Coding System Design

I applied online and heard back within about a week. A recruiter call was next, which was more of a casual chat about my background. Then came the onsite interviews at the Tinder office. The recruiters were super welcoming, and the office vibe was really chill and collaborative, with everyone seeming passionate and happy. The interviews themselves were different from the usual; the interviewers were enthusiastic and made me feel comfortable, so I didn't feel nervous or drained afterward. The questions were tailored to my resume, not generic algorithm problems. They focused on getting to know me and assessing my fit, with a couple of straightforward coding questions and some design questions. Post-interview, a recruiter explained stock options clearly, which was helpful as this might be my first job. They were also open about the realities of working at Tinder, sharing personal experiences. Honestly, compared to my experiences interviewing with the Big 4 and other companies, Tinder's process was the best – they really respect candidates and prioritize making them feel comfortable.

Technical Coding System Design Behavioral

It began with a recruiter call which was super chill and welcoming. Then, I had an engineer call where I talked about my past work and solved an OOP problem on Codepad. After that, I went onsite and had several interviews. Two of them were design interviews where they asked me to talk about my past projects and how they were built, and two were coding problems.
