Tokopedia Interview Experience for Software Engineer (1+ Year Experienced)

Round 1: Online Coding Round: The first round was an Online Test conducted on the Hacker Rank platform. There were around 10 MCQs in this round related to Android and OOPs concepts and 1 coding question was there. The coding question had more weightage. Here is the question:

• https://www.geeksforgeeks.org/find-element-array-sum-left-array-equal-sum-right-array/

I was able to solve most of the MCQs correctly and also passed the coding question with all test cases. I was selected for the 1st round of Technical interviews.

Round 2(Technical Interview Round 1): This was a DS+Algo round and the interviewer shared the code editor and 3 questions were asked. The interviewer asked me to explain the approach first and then start coding for each of the questions.

Here are the questions:

• https://www.geeksforgeeks.org/remove-all-duplicate-adjacent-characters-from-a-string-using-stack/
• https://www.geeksforgeeks.org/move-zeroes-end-array/
•  https://leetcode.com/problems/group-anagrams/

I was able to solve all the 3 questions and hence got selected for the next round of interviews.

Round 5(HR Round)1: This was the final round which consisted of some basic HR questions followed by a Salary Discussion. 

The entire process took around 1 month and finally I was selected.

All the best!!
