      Backend Developer Interview

      Average interview

      Application

      I applied online. The process took 1 day. I interviewed at IBM (Toronto, ON) in Jan 2021

      Interview

      I applied online and after 1 week, I received the online assessment. It was in two parts, the first was Cognify Game Assessment, and the second was the HackerRank coding assessment. The cognify assessment was divided into 5 mini-games which were to check problem-solving skills and skills with numbers. They were easy but with very little time hence it could be a bit unnerving. The HackerRank coding assessment was easy. 3 questions 3 hours In the beginning, I felt that it is very easy as I completed the first 2 questions in under 20 mins, but the last one was a bit tricky. The logic was simple but it was exceeding the execution time limit for some test cases. I tried my best for 2 hours, but could only get 5/9 test case passed. Now I am waiting for the response, let's hope for the best. 🤞

      Interview questions [1]

      Question 1

      The 3 coding questions were: Searching in the string; Basic File I/O operations; Triplet count based on conditions
