Candidate interview experiences
First-hand accounts from people who interviewed at Lumen.
Data Scientist
The difficulty is moderate to easy. Like any other interviews, it depends on the position and team you are being hired for, the questions were majorly from domain I worked on and technical knowledge used.
- Tell me about your use of the random forest algorithm and how you would determine NPS for a user.
Data Scientist Intern
I applied online and got a HireVue interview right away. I thought I did great on it. Then, after two months of no news, I found out I didn't get the job via email. I ended up getting a better internship elsewhere. I wouldn't suggest applying here; it's a waste of time.
- Tell me about a time you faced challenges working in a team.
Data Scientist
To be considered for this role, you'll need to complete an exercise. We suggest finishing it within 5 days of applying. This exercise involves answering some questions and playing some Game Challenges. You'll get to practice before each question, and each game will have its own set of instructions to read beforehand.
