Overall it was a good interview process, the coding assesment was very good and had MCQ s as well as dsa questions . practice well and it's not hard to crack.

This is my experience about the first round of SRE intern hiring in linkedin which is done on hackerrank. Out of total 31 questions the exam had 3 coding questions 2 sql questions and rest were CN, OS and unix questions. Everything was easy and more emphasis was given on CN.

Questions mostly on linux/unix. Two of OS related coding questions - included concepts of multithreading and semantics. Some MCQs were easy given you revised the concepts they put under requirements and the time limit was gracious.
