Paytm came to GL Bajaj campus for recruitment of SDET role. There were 3 rounds held in the complete process:

  • Online Assessment
  • Technical Interview- I
  • Technical Interview- II

Online Assessment Round: OA consists of a total of 17 Ques (15 MCQ+ 2 coding ques). Coding questions are:

  • 1st question is recursion based and the question was the variant of Combination Sum I was able to do it with all test cases completely pass.
  • 2nd was DFS traversal based and I was not able to do it.
  • MCQ questions were based on the Analysis of Graph, basic aptitude questions and some are from the core CS subject like Operating System, Computer Network based questions. I was able to solve 12 out of 15 questions.

The result of the OA round depends on both i.e. Coding and MCQ-based questions as many of my friends do both coding questions but they are not shortlisted because of not doing MCQ questions. So both sections are important.

Result: The result came with a list of shortlisted 72 students including me.
