I did not succeed in qualifying for the next review level.

The interview lasted for one hour and thirty minutes. The interviewer was very nice and kind. The review was conducted via Zoom.

The first question was a program algorithm which receives a pointer of char* and needs to return a series of characters.

For example: if the char string is aabbbccd, the algorithm needs to return a2b3c2d1.

The second task involved a global array with the size of threads and one function which prints the IDs of threads. The task was to complete some rows before the printing and some rows after printing in order to print all IDs of threads in a well-ordered, non-colliding manner.
