I recently had the opportunity to interview for a software Engineering role in Crest Data Systems (ON-CAMPUS). While the interview process was challenging and ended with a rejection, I believe that sharing my experience can help others.
Initially, there was an Online Assessment Round (4 coding questions ).
Around 90 students were shortlisted after OA for the interviews.
Technical Round -2
- The first round was a technical assessment. First I was asked to introduce myself. After that, they asked me about Compiler and interpreter. After that, I was asked coding questions around 3-4 which were easy.
- Q1. To find the largest element present in the array
- Q2. To find the second-largest element in the array
- Q3. Check if a string is an anagram or not
- Q4. Implement push and pop operation in stack
- Also, they asked me about the time complexities for the same.
- They then asked me about the types of data structures and the difference between stack and queue.
- Then they also asked me about the OOP concept, asked me to tell about OOPs, and its four pillars, and also explained, function overloading and ridding, and asked me to write the pseudo-code for inheritance.
- They also asked me about the Http Request Protocols . Difference between GET and POST. When do we use GET . What are cookie?
- They also asked me questions regarding SQL -about joins,Types of joins, indexing , types of indexing , what is commit and rollback, they asked me to write a query for showing inner join.
I was unable to perform well in the SQL part .
Technical Round – 2:
The interviewer first asked me to introduce myself and also asked me to give brief about projects that I mentioned in the resume.
Then they gave me 2 coding problem , medium level, I only remeber one coding problem that was Group Anagrams , which is available on leetcode and also I was able to only give the approach for the problem.
The second coding problem that was asked was a bit tough for me and I was unable to solve that problem. I don’t rember the problem but it was from codeforces I guess.
After the two technical rounds I was rejected and was unable to go for further process.
But overall it was an amazing experience !!!
