redBus Interview Experience for Software Engineer | On-Campus 2021
Redbus visited our campus in the month of September 2021 for Software Engineer role. The shortlist for the online test was done on the basis of 2 parameters:
- Parameter 1: 10th & 12th/Diploma marks – 87% & above
- Parameter 2: BE CGPA – 8.5 & above
Round 1(Online Test): Test was moderate with 23 MCQs and 3 programming questions. MCQs were fine with questions on java concepts, c++ code snippets, and moderate aptitude questions. Coding was a bit tough.
One of the questions that I remember is:
Write a program in the language of your choice to find out how many minutes M will it take for a phone to reach from charge A to charge B (A and B are inputs, M should be the output). The rate at which it gets charged at different levels was given.
For example: 0<= C <= 10 : 8 mins 11<= C <= 50 : 6 mins And so on Sample: If A= 0 and B=5 then M is 8 because in 8 minutes it reaches 10 charge which is greater than 5.
Getting the output for at least 1 program along with decent performance in MCQs was sufficient to clear the test.
46 out of 211 students were shortlisted for the next round
Round 2:(Technical Interview 1):
