Media.internet visited our campus for the Web site Reliability Engineer function (DevOps) in August 2022. CGPA standards had been 6 and above.
There have been 5 rounds.
Spherical 1: (On-line take a look at): It was an MCQ take a look at, I don’t bear in mind the period and variety of questions. It had questions from Working Methods, Laptop Networks, Information Buildings and Algorithms, DBMS, and Basic Aptitude.
Round 23 individuals bought chosen for the Machine Spherical and I used to be one in all them.
Spherical 2: (Machine Spherical – Offline, 3 Hours): This spherical was carried out in our laptop heart. We got a socket programming activity.
Process Description: There’s a server that has key-value storage. There could be a number of shoppers which might ship requests like ‘GET’, ‘PUT’, and ‘DELETE’ to the server.
The important thing-value storage, server, and consumer code is written all from scratch. We had been allowed to google something like syntax, errors, and so forth. We had been even given the choice of selecting any language we had been comfy with, I went with Python.
- The important thing-value storage is principally a dictionary in python. So I’ve written a category which has a dictionary in it and a few features to take care of the ‘GET’, ‘PUT’ and ‘DELETE’ operations.
- I wrote code for the server which might be prepared to just accept shoppers and may begin speaking over TCP protocol, equally, I wrote code for the consumer which might be able to take enter from the person for the requests and ship it to the server.
- After I used to be finished with the duty, I nonetheless had a while left, I used to be requested to implement a TTL(Time to dwell) system for the storage. Which means a key could have a time-to-live part, the important thing would expire after a sure time frame. I implement this and the time was over.
- Since I used to be utilizing threads to take care of a number of shoppers, I had to make use of threads. I used to be requested if my code was thread-safe, and I mentioned no as a result of my primary goal was to complete the essential activity and implement thread security later. The interviewers had been pleased with it although.
3 college students made it by means of this spherical, I used to be one in all them.
Spherical 3: (Technical Interview – Offline, 1 Hour): This spherical was a CS basic principally associated to Working Methods and Laptop Networks.
The interviewers greeted and launched themselves and requested me to introduce myself. The interviewer went by means of my resume and requested me about my internship.
Then the dialogue went in the direction of Laptop Networks, a number of the questions I bear in mind had been:
- What are TCP and UDP and the way do they work.
- 3-way handshaking.
- What occurs once we kind google.com in our browser?
I had talked about Git as a model management system in my tasks in my resume, so he requested me a query associated to it.
- Let’s say now we have an utility. Version2 of the applying has been deployed and now after 5000 commits, now we have deployed version3 of the applying. We now have came upon that the ultimate version3 has a bug, which had crept in from one of many commits. How would you discover the commit through which the bug began?
- A follow-up query, an identical scenario is given however this time the bug began in one of many commits and in addition bought resolved in a later commit, making version3 nonbuggy. We now have to search out out the place the bug began this time.
Spherical 4: (System Design – Offline, 1 Hour): This spherical was a System Design spherical.
- The interviewers greeted and launched themselves and requested to introduce themselves.
