Celigo Interview Experience for SDE | On-Campus 2021

Celigo came to our campus in mid-August 2021 for SDE profile. They were offering 6 months Internship (from Jan 22 -June 22) with Full Time Emp. thereafter.There were 4 rounds namely:1 Online Coding test2 technical interviews and1 HR interview round. About 140 candidates applied .All branches’ students were eligible for appearing in coding test(except metallurgy.)Round 1: Coding testThe test was conducted on the Hackerrank platform on 2nd Sept. It consisted 22 MCQ + 3 coding questions.The MCQ consisted of questions related to binary trees traversal.Debugging, analytics, basics of precedence and associativity, MACROS pointers, data structures, etc. coding questions were based on Inversion count in an array, Job scheduling problemFinding a pair of points with minimum distance. The time allotted was 120 minutes.Those who cleared all these questions correctly were invited for technical interviews (about 20 students).I think that I scored almost 100% on the coding test.Round 2: Technical InterviewIt started with a basic introduction. The interviewer was very polite and friendly. Asked about the project I did during the summer internship.Tried to answer all questions.After 15 minutes of project discussion, we moved to DSA. The interviewer gave me 2 questions: a) searching an element in a rotated sorted array(using binary search), b)given a value of n, print all valid parenthesis strings of brackets(). Although I tried my best, he was not so satisfied.(He liked the approach but found code confusing). This round went about 90-95 minutes long. After 30 minutes I received a link for the third round( second technical interview).Big relief 🙂 Only 10 students were selected further.Round 3: Technical Interview:Again I found the interviewer was very polite and supportive. She provided guidelines to proceed during the whole discussion. Asked to introduce myself. Long story short,she asked three questions:Count pair of numbers whose sum is equal to a given target(all corner cases, edge cases had to be handled and taken by you yourself)improved same question to three sums equal to target (all cases of negative, positive, similar, dissimilar elements)A variant of maximum overlapping intervals(greedy approach using Line sweep).discussed a game and asked to implement it (I guess system design).The maximum allotted time was about 90 minutes, but it went like something 125-130 minutes. Additionally, 10 minutes when I asked questions about their role in Company and atmosphere. 6 students moved to the HR round.Round 4: HR roundIt happened about 1-2 hours after the second technical round. Went about 10 minutes long. Good and smooth.Questions were the same as you expect in any HR round.Finally, 3 students were offered the role. Thankfully I am one of them.Tips:Keypoints for an interview: Be clear about what to say and make sure your interviewer is listening to you and understanding your approach to solving problems.Speak what you write: it makes an impact…Be with the pace of the interviewer. Always read the company details and Job description thoroughly before interviews.All the best for your interview by the wayAttention reader! Don’t stop learning now.
