Zomato Interview Experience for SDE Intern (On-Campus) 2022

Round I
The First Round was an online coding round where two very simple DSA questions were asked. The duration of the test was 1 hr 30 min. The questions were not very simple but luckily brute force approach worked in both of them. Almost 60 students appeared for this round. 10 students were shortlisted from this round.

Luckily I was one of them. Many students were able to solve both of the questions. But, the final shortlisting was done based on CGPA , If both of the questions were done. Before this round, there was a resume shortlisting. When they appeared, they gave us the option to choose either 6 month or 2-month SDE internship. Those who chose a 2-month duration were simply out of the further rounds. Choose carefully.

Round II
For me, this round was scheduled at 6 a.m.
This round lasted for 1 hr. The interviewer was very friendly. He first started with my resume and asked about my projects since I have worked on PHP i.e., the backend part of the project. 
The questions I was asked are as follows :

• How do you do password validation?
•  Write that part of the code which does this ?
• Simple Oops concepts like polymorphism, inheritance, etc.
• Some questions are based on indexing and paging in DBMS.

This lasted for about 20 minutes. Then I was asked a DSA question.
I was given an expression without brackets and I was asked to validate this expression.
Then he added some brackets and I was asked to validate that.
Now, the last part was to calculate the final expression. 

Some Questions that other candidates were asked are as follows :

• Detect Cycle in the Linked list
• CPU scheduling algorithm
• Rapid fire on all DSA concepts like a queue, stack, binary tree, etc.

Finally, after 2nd round, 2 students were shortlisted.
