SplashLearn Interview Experience for SE | On-Campus (Virtual) 2020

Splashlearn visited our campus on 3-oct-2020 for SE. Branches allowed CSE, IT, and ECE there were four rounds in total.

First Round(Online test): This was an online round conducted on https://mettl.com. There were four questions in total to be solved in 90 mins

1. The first was an easy one where brute force will work 
2. The second was the longest palindromic subsequence
3. Third was (delete and earn problem) from leetcode
4. The fourth was a little tougher based on a directed graph BFS where we have to go from source to destination in minimum time. Question was: You can take the bus from the source (bus number was also given) and if you go from one stop to another(take an edge). Then the time cost will be 1 unit and if you change the bus from any stop additional time of 1 unit will be cost .find the minimum time in which we can go from source to destination. 

13 people sortlisted from more than 200 people

Second Round(Technical): Apart from the introduction there was a deep discussion on the implementation of the ranking table(very similar to the IPL table)

If points are equal then the net run-rate if it will also be equal according to the name. Where we have to maintain the sorted order of the team in the table. There was a deep discussion on this question complexities at each and every operation I used maps and set with comparators to implement the table.

He was more focused on pseudo-code instead of syntax

6 students qualified for the next round

Third Round: Three questions were asked in this round. Same for every candidate

1. The first was on coding and decoding

2. The second was Convert 33 to 933 with minimum operations

   Operation allowed:

   Divide by 10
   Multiply by 10
   Increment by 1
   Decrement by 1
