Crest Data Systems Interview Experience (On-Campus)

Crest data systems came to our campus for offering internships and jobs to final-year graduates. There was 1 online round, 1 technical round, and 1 HR round. All the interviews were conducted physically on campus. There were 3 roles. Software engineer, Site Reliability Engineer, DevOps Engineer. I appeared for the Software engineer role.

Online Round

• The first section contains easy programming questions. There were 2 questions. Time duration ( 45 mins ).
• The second section contains debugging questions, and the level of difficulty was easy to moderate. There was 7 code fixing questions. Time duration ( 20 mins )
• The third section contains 2 programming questions. level of difficulty was medium to hard. Time duration (60 mins).

Suggestion: Anyone with good knowledge of data structures and algorithms can easily pass the online test.

60 people were shortlisted after the online round.

Round – 1 (Technical Interview)

• There were 2 interviewers. The interview started with an introduction.
• After that some questions based on the projects and internship. I was asked to write a simple react function program.
• Then shifted to data structures and algorithms. They asked which sorting algorithms I know, and I listed down some of the most popular sorting algorithms. Then he asked me to code merge sort. I quickly coded it. I give O(log N) solution. They satisfied.
• Then they asked me to code out a binary search. first on numbers then on strings. I give O(log N) solution.
• Then they asked the question for finding occurrences of every character in a string and printing out but the order should be maintained. I give the O(n) solution using maps and vectors.
• Then they asked the question about generating permutations for a given array.
• Then they asked me computer science fundamentals questions about operating systems and object-orientated programming. from operating systems, they asked about processes and different scheduling algorithms from object-orientated programming they asked about polymorphism and abstraction.

Suggestion: Be calm and know everything on your resume.

for some of the people, there were 2 rounds of technical interviews.

33 people were shortlisted for the HR round.

Round – 2 ( HR Round )

• The interviewers were very friendly and they asked me about my hobbies and interests.
• Asked about strengths and weaknesses. Asked about internship experience, and problems faced in projects. Some of the behavioral questions were also asked.

Suggestion: Be calm and cool.
