Easy Interview
Application

I applied through a recruiter. The process took 1 week. I interviewed at Ciena

Interview

recruiter from their company reached out wanting to see if I had an interest in the role. I kindly asked what the base and OTE looked like. They would not disclose this even though I politely asked them a few times I wanted to know upfront. They wanted me to fill out an online application etc. I was not interested in jumping through hoops and wasting my time if they couldn't even give me a range of pay. RED FLAG. Avoided.

Interview

Got contacted by recruiter who asked why I'm switching jobs, if I'm applying anywhere else and why I'm applying to ciena. Then interview with hiring manager who told me about the role and went over my resume. He said next interview would be technical. Then got contacted by recruiter again asking if I'm still interested and she booked a second interview. Second Interview was 3 guys asking about my past experiences, and asking questions based on the work I had done. Then contacted by recruiter again to see how I feel if I'm still interested.

Interview Questions
  • Interviewed for a junior role, the questions were all based on work I had done previously. Nothing too technical or detailed. Questions like: Tell me about a difficult project you worked on, What do u do when you are stuck on a task?

I applied online. The process took 2 days. I interviewed at Ciena (Ottawa, ON) in Oct 2022

Interview

I was told to have a 30-min phone calls. The interviewer is polite and friendly. He introduced to me what Ciena do and what skills he was looking for from a candidate. It’s my problem that thought it was only a BQ interviews or discussion of my previous experience so I didn’t prepare any for the Basic definition of the C language, I know that’s only the basic definitions. Some questions I even knew the answers but I was kind of lost and couldn’t answer it well. I recently had interview with Java and I perfectly answered them well. So It’s just I didn’t prepare to answer such questions…My advise is GET PREPARED!

Interview Questions
  • What data types do C has? What’s the difference between static and global variables? How do we store static variables? What are the ways we call variables from a method? What is the differences of them? etc.
