Summary

I cleared all interview rounds for the SE3 role at Paypal in February 2025, but unfortunately, no open positions were available after a process that took over a month, leading to disappointment due to lack of clear communication.

Full Experience

Online assessment: 2 questions

1st round : DSA

  • LRU Cache
  • Take substring from string this way that shortest length remains

2nd Round : Java and HLD

  • Java and spring boot questions
  • Hackerrank question
  • Implemented design patterns
  • HLD: Loan Management App

3rd Round

  • Role Specialisation
  • Hackrrank question on writing springboot apis

4th Round

  • Bar Raiser
  • Just behavioural questions and discussion

The process took almost more than 1 month.

Received email that I’ve cleared all rounds but no open positions. Disappointing as no clear communication and not picking calls when tried to reach out.
