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.
