Round 23 individuals received chosen for the Machine Spherical and I used to be certainly one of them.
Spherical 2: (Machine Spherical – Offline, 3 Hours): This spherical was carried out in our pc heart. We got a socket programming process.
Job Description: There’s a server that has key-value storage. There could be a number of purchasers which might ship requests like ‘GET’, ‘PUT’, and ‘DELETE’ to the server.
The important thing-value storage, server, and shopper code is written all from scratch. We had been allowed to google something like syntax, errors, and many others. We had been even given the choice of selecting any language we had been comfy with, I went with Python.

- After I used to be carried out with the duty, I nonetheless had a while left, I used to be requested to implement a TTL(Time to reside) system for the storage. That means a key could have a time-to-live part, the important thing would expire after a sure time period. I implement this and the time was over.
- Since I used to be utilizing threads to cope with a number of purchasers, I had to make use of threads. I used to be requested if my code was thread-safe, and I stated no as a result of my foremost intention was to complete the fundamental process and implement thread security later. The interviewers had been comfortable with it although.
3 college students made it by way of this spherical, I used to be certainly one of them.
