Round 1- Online Assessment(70 mins): 3 coding questions – we couldn’t resubmit the code once submitted
- Finding the third largest string in a given array
- Find the missing digit x from the given expression
- Fizz Buzz
9 MCQs based on DSA, CN, OS, and Linux. Both the codes and MCQs were simple so your accuracy mattered the most
Round 2 – Technical Interview(45 mins):
- The interviewer didn’t ask the usual q of “Tell me about yourself”
- He asked about my comfortable coding language
- Asked about the 4 pillars of OOP
- Asked to explain each one in detail with example
- Then asked me the difference between overloading and overriding
- Told me to write a code to show both of them
- He then asked me what is abstract classes
- Further, he asked about the difference between interface and abstract classes
- He then asked about lifecycle hooks in React (I had a couple of React JS projects on my resume so)
- Asked 3 DSA code all of the arrays and easy – medium difficulty
- He then asked me what happens when you search anything on a browser – I first told him DNS resolution and then was trying to explain by OSI model, but he saw that I could write all layers of the OSI model so he was satisfied
- He then asked me if I wanted a Full Stack Role(most of the projects were in this area)
Round 3 – Techno-HR (1hr 30 mins): I just came out of the technical interview and within 10 minutes I was called for this round
- I was asked about my GRE, GMAT, GATE, and CAT scores
- I was then asked about my favorite project from my resume
- We then discussed project architecture for 30-35 mins
- He then moved to OS
- Asked basic questions like what Multithreading, Paging, Segmentation
- He then asked me, if I were given a 30 GB text file and I have to search a word in it then what approach will I use (took around 30-40 mins)
- He then asked me about my hobbies
- After that, he gave a hypothetical situation if Musk was to colonize Mars and if I was to be tasked to setup Facebook for Marsian people then how will I do it from an implementation point of view
There was no HR round
Out of 40 students selected for the interview, only 6 were selected. I was one among them.
Druva’s main focus was OS – So I’ll suggest first solving MCQs, refer Fraz’s OS Sheet, and if time permits, watching Gate Smashers.
Thanks, GFG and all other fellows students who uploaded their interview experiences
