GreyOrange came to our campus around the month of November-December.

Round 1 OA The first round was an online assessment consisting of 10-15(not exactly remember) MCQs based on Object Oriented Programming in Java and one simple coding question in Java. I cleared this round and was selected for interviews afterward.

Round 2 Technical Interview I am listing down as many questions as I could remember were asked in this round: Difference between C and C++. Difference between Machine Learning and Deep Learning. Define OOP. Their types. Explain them. Difference between linked list and array. Define enumeration. What would I do if I wanted to check if the company's telephone is working properly or not? Difference between primitive and dynamic data types. Difference between function overriding and overloading.

Coding Question 1: Check if the given string is palindrome or not.

Coding Question 2: Check whether an input year is leap year. These were the simple questions asked. She grilled me on CS fundamentals and asked about 25-30 questions. This round went for 35 minutes and cleared this round pretty easily.

Round 3 Technical Interview After round 1 was over, those who got selected for Round 2 received interview links for this round after 30 minutes. The interviewer was not impressed that my expertise was C++ and not Python. He directly asked me why I chose this language or what is the reason behind choosing this language. This information is important that their company predominantly works with Python so me using C++ was a disadvantage. I assured them that I was learning Python as I wanted to dwell into Machine Learning and AI. So the questions asked in this round were: Explain Software Development Life Cycle. Explain waterfall model. Difference between SQL and MySQL. Then there were other CS fundamental questions which I was able to answer.

Coding question 1: Print all the subsequences of a given string of length 2. There was another coding question which I cannot not remember. Then he asked me if I had experience working with Linux operating system. Then asked to name a few Linux commands. He also asked to name some Linux commands used for string manipulation, which I could not answer. Overall, I think I could not answer 2-3 questions. The margin for error is really low when the competition is high. This round also went for 35 minutes.

Verdict

Rejected
