The Technical Phone Screen: What to Expect and How to Prepare

The technical phone screen is often the first real technical evaluation in the hiring process. It typically lasts 45-60 minutes and covers basic coding, problem-solving, and technical discussion. While it's usually easier than the onsite interviews, it's still an important filter that you need to pass to move forward.

What to expect

Expect a mix of moderate-difficulty coding problems and technical discussion. The interviewer wants to confirm that you have the fundamental skills to make the onsite worth their time. Be prepared to discuss your experience, technical decisions, and approach to problem-solving.

Preparation tips

Review fundamental data structures and algorithms. Practice coding in a simple text editor or shared document — you won't have IDE features during the screen. Prepare your environment: a quiet room, reliable internet, headphones, and water. Practice explaining your thought process aloud while coding.
