Interview
The whole process took less than 3 weeks.
1. A quick 30 min call with the recruiter to go over your resume. If they like you, then you'll interview with a manager.
2. The first technical interview with the manager was an hour long and we went through my experience, the manager's experience and then a coding question, it was an easy-medium linked list coding challenge.
3. If you get to the final round of interviews, you will be interview by 4 people in a half day long interview of 4.5 hours. One hour each person and 30 min for lunch break. This round of technical interviews is the more tiredsome and the coding questions are not bad either.
I realy suggest you to keep doing leet code and hacker rank medium-hard problems beacuse these people expect clean, almost perfect O(n) O(1) answers, in a spam of 30 minutes. This was my first time doing this style of interviews and for me (i got VERY anxious) it was brutal, though the questions shouldn't be that bad to solve, they expect you basically to respond like chatGPT and even comment your code.
I think this is achievable if you get time to practice at leas 3-5 medium to hard exercises daily on leetcode for AT least a month. I only did like 30 exercises in total and they don't care that you did a brute force approach to the problem first, if you don't have time to give the best answer to the problem, they'll probably will not make you an offer.
Interview questions [1]
Question 1
They asked a lot of behavioral question in between the lines and those were fine, no funny business there and the coding questions were about:
1. string manipulation
2. bit manipulatioon
3. hash tables (or the closest you can pull on c and c++)
4. bytes manipulation and memory alignment
everything was in C and nothing about dinamic programing.
If you really want to get an offer from a company like this, I strongly suggest to really polish your programming style, your knowledge of the language, like really master C or C++, they don't care that you understand the problem from a high level perspective, these people are trained to select a candidate that can give the right answer to the coding challenge in the right time and discuss the answer.
Recruiter -> Technical: Only got to the technical round, and the process was pretty smooth and fast. Not much to complain about. The recruiter was very friendly and responsive throughout the interview process.
I applied online. The process took 4 months. I interviewed at Snap (Paris) in Apr 2024
Interview
The worst recruiting process I have had in my life! I got contacted 4 months after sending my application. The first interview was a friendly visio chat with an HR. After that, I was invited to a second interview (also visio) that would be technical with the hiring manager. It was supposed to be a live coding challenge to which I prepared very seriously. On the day of the interview, the hiring manager showed up one hour after the scheduled time. He said that the HR messed up with the timing. The interview turned out to be a discussion where I had to present myself, no live coding challenge... After that, I was invited to an onsite interview that was composed of 4 interviews in a row, starting at 09:00 am and finishing at 03:00 pm. This interview got rescheduled 4 times over a month, with less than a 48 hours notice each time. The 4 interviews were technical and extremely difficult with plenty of difficult and extremely trick questions (and I wonder why. It was completely disconnected from the reality of a day-to-day embedded software engineer life). At the end of the day, I knew I wouldn't get the job but I never received a feedback. Not even an automatic message.

Question 1
Explain what this function does to me (at the blackboard, without any support):
void func(char* a, char* b)
{
while(*a++ = *b++) {}
}
