Technical Behavioral
The interview process was easy but felt dehumanizing because of the asynchronous video component. I wish they'd get rid of it. The questions overall were easy and superficial. Each question had a one-minute time limit, and you couldn't pause to think when retaking. I didn't like how the recruiters seemed to be making the process easier for themselves.

Behavioral Coding Technical
The interview process was really smooth. I had a phone call with the recruiter who explained everything and what to expect in each interview. My recruiter was super helpful. The first round was a 15-minute behavioral interview focusing on a specific topic, followed by a 45-minute coding session with Leetcode-style questions. If I passed that, I was invited to a super day with three more interviews, all following the same format as Round 1. My experience with most of the interviewers was great; they were very nice. However, one interviewer was incredibly rude. He spent five minutes explaining a problem without pasting it and expected me to remember everything. The problem wasn't even a standard Leetcode question. He seemed intentionally difficult and even mocked my hackathon projects for using LLMs. I'm confident I passed all interviews, and he was the only issue. It felt like he didn't want anyone to get hired. Snap, you should really address this.
Confirmed questions3 questions
- Medium-hard Leetcode-style problems were asked.
- For behavioral questions, they focused on different situations and how you handled them, rather than your resume.
- Each interview covered different behavioral questions.

Technical Coding Presentation Behavioral
So first I had a call with the recruiter, then a 1-hour call with the manager where they asked me some C++ questions and one LeetCode problem. After that, the final part was a virtual onsite, which had 5 interviews. The very first one was a panel presentation where I introduced myself, met the team, and talked about a past project. Then, there were four 1-hour one-on-one interviews, each with one of the engineers from the panel.
Confirmed questions4 questions
- Could you answer some theoretical questions about C++?
- Can you explain concepts related to threading in C++?
- What is the difference between std::forward and std::move?

Quoted word for word from Snap interview reports.
“Given a pattern and a dictionary, print all strings matching the pattern where dictionary characters are uniquely mapped from pattern characters. For example, for pattern "abc" and dictionary <"cdf", "too", "hgfdt", "paa">, the output should be "cdf". For pattern "acc" and the same dictionary, the output should be "too" and "paa".”
