Entretien
My interview was a phone interview that required me to ssh into their servers die a technical coding interview. The coding portion took around 20 minutes, and the remaining time of the 1 hour interview involved questions on data structures and talking about what I have done and my experiences. The coding portion was implementing functions of a binary search tree. The other questions asked by mouth were on things like linked lists, comparing singly vs doubly-linked, their time costs, etc. All in all, there was a big focus on data structures.

Question 1
I was asked to implement some functions of a binary search tree such as finding the next node with inorder traversal. It was then tested with pre-written tests. This was all done in C.

Pros:
Great initial approach – the recruiter thoroughly checked my GitHub profile and projects before the interview, which is very uncommon and shows they do their homework.
Cons:
A major mismatch between the job description ("Software Engineer C++") and the actual interview reality. The technical stage on CoderPad strictly tests bare-metal C98 skills: raw pointers, manual bitwise operations, and packing bytes into 64-bit integers. If you are accustomed to modern C++ (RAII, templates, safe memory management), this will feel like a massive step backward. Additionally, the time expectations for live low-level bit-shifting were unrealistic, to the point where the interviewer started solving the task themselves.
Interview was kind and not stressful, just minor mismatch of naming

Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
Starts with online test, then three rounds of technical interviews follow.
Not a lot of discussion, just go straight to the technical challenges which have to be solved in time
