The same day that I applied online, I was contacted to schedule a phone interview (Phase 1). The phone interview was a few days later with 3 TELUS employees (HR, Director of the LDP program, etc.). I was asked a few questions about TELUS and what I knew about the company (strengths, opportunities for improvement). Then, there were a few standard behavioural question (Name a time you dealt with conflict). Afterwards, there was one technical question. Overall, the phone interview was about 25 minutes and a positive experience. It was a bit awkward with so many people listening in over the phone: it's hard to gauge when it's someone's turn to speak, since you can't see their face or body language.
I was notified within 2 days that I had moved forward to the second phase, which would be an in-person interview. I was told that someone from the company would be contacting me within a week to schedule an interview, when in reality, I was contacted nearly 3 weeks later to schedule it! The time between my first and second interview was almost a month. The second interview consisted of a Case presentation (given 1 hour to prepare it and 30 minutes max. to present it to 2 interviewers), as well as a one-hour behavioural interview. Mostly typical questions, such as "Describe a time when you had to work with ambiguous instructions".
They also require a reference and background check.
Both interviewers seemed nice and friendly. The interview was difficult in the sense that it was challenging, but if you were well-prepared, it was straightforward. The only thing I didn't like was that the case was a bit long to be well-done in an hour. I guess that's the point, though! Another point: the interviews are very scripted- your interviewers are basically filling in a worksheet with your answers. It felt a bit impersonal (no "tell us about yourself", etc.) because of how prescribed the questions were.
