1. Overview of the PayPal Interview Process

The PayPal interview process is known for its rigor and focus on assessing both technical expertise and cultural fit. It typically involves the following stages:

1.1 Online Aptitude Test

The first step in the PayPal hiring process is an online aptitude test that includes technical and coding questions. This test is administered on HackerRank and evaluates your problem-solving abilities, coding skills, and aptitude.

1.2 Technical Rounds

Once you clear the aptitude test, you will proceed to the technical interview. There are typically two rounds:
  • Face-to-Face Interview: Focuses on coding skills and problem-solving ability.
  • Problem-Solving Interview: Involves coding challenges that test your approach to solving real-world problems.

1.3 HR Round

After clearing the technical rounds, you will face the HR interview. This round assesses your personality and fit within the company culture. HR will ask questions related to your resume, motivations, and career goals.
