I applied through an employee referral. I interviewed at ZTE (Tianjin, Tianjin) in Jan 2022
Interview
The interview asks the questions about C++ like the difference between the stack and heap, how the garbage collection works and what is dangling pointer. The second round is about the character questions.
round 1: online test, several telegram questions, python questions, cs questions, 2 programming
round 2: on-site interview, two interviewers, trying to know something about your project at school, and they also ask very simple questions about telegram. I guessed it depends on your background
Test was a medium level of difficulty. The whole process is alright. I just took too long and can't come up with a solution. Just practice more leetcode questions and be ready for the interview.
