1. Technical Phone Screen

What It Is:

A technical phone screen is usually the first step in the interview process. It involves a phone call or video call with a recruiter or engineer who asks you coding questions to assess your basic technical skills and problem-solving ability.

How to Prepare:

• Review Basics: Make sure you are comfortable with basic coding concepts and can solve problems quickly and accurately.
• Practice Out Loud: Practice explaining your thought process and solutions out loud, as you will need to do this during the interview.
• Common Questions: Focus on common questions related to data structures, algorithms, and basic problem-solving.

How to Excel:

• Clear Communication: Communicate your thought process clearly. Explain each step as you work through the problem.
