I applied online. I interviewed at Synechron (Montreal, QC) in Jan 2026
Interview
10 minute phone call followed by a 30 minute technical screening. The interviewer was extremely unprofessional, kept asking questions too fast and did not clarify questions when asked. They kept telling me to just answe without thinking or aksing questions. They looked in a hurry to finish all the questions in interview and kept rushing for answers, often sounding rude.
I did not complete the interview i dropped from the call!
I was not able to answer basic simple question of stream as usage of IDE was not allowed it was in online compiler.
Anyways, the interviewer was dead rude from the beginning, I would not want to work with those kind of people for sure.
