I applied through university. I interviewed at ServiceNow (North Twenty Four Parganas) in Aug 2018
Interview
Online Test - Aptitude + Technical ( 30 questions in 30 mins) followed by PPT .
It mainly focus on quantitative aptitude, logical reasoning, Operating systems, Data structures and Algorithms.
2 Face to Face technical interview rounds.
1 hr interview round.
Interview questions [1]
Question 1
1) A stream of numbers coming. Find the top 5 numbers.(binary heap)
2) Find a ring in a list of strings.
The process was unclear and the recruiter was not very organized. There was a lack of communication and even conflicting meetings. I would think it's something specific to this recruiter/instance.
i havent selected but i understood that minimum basics of cs is needed. they asked some DSA questions and also SQL and DBMS questions. it was online and it is of 3 rounds
