Difficult Negative Canada

I had an interview that split into two parts—one interview went well, and the other was with a client. The first part felt positive and comfortable, but the second part didn’t really progress the way it should have, because I experienced it as being ignored rather than actively interviewed.

Even with that disruption, the overall process still felt fairly smooth and calm for me. The difficulty was hard on paper, but the emotional hit came from how the client-related segment played out rather than from the complexity of the questions.

Average Positive Tormore, ON

My process started with an HR screening, then I moved into a live technical screen, and after that it turned into management-style discussions. The overall difficulty landed in the average range, and the structure stayed pretty consistent—each round built on what I’d already said about my background.

In the communication part, it was basically a spoken English style assessment using an automated voice flow. It tested things like reading and repeating, short spoken responses, and listening comprehension. After that, the technical assessment covered both coding and theory—DSA basics, SQL queries, and multiple-choice questions around CS fundamentals like DBMS/SQL, operating systems, computer networks, and OOP concepts.
