Zuora Interview Experience (On-Campus)

Zuora visited our college for a 6-month internship + PPO.

• Round 1: Online Assessment
• Round 2: Technical Interview 1
• Round 3: Technical Interview 2

Round 1: Online Assessment: Round 1 was an online assessment conducted on HackerRank. It consisted of 6 sections. There was one coding question. All others were MCQs on DBMS, OS, CN, and Linux. Webcam access was enabled. I was able to solve all the questions.

Round 2: Technical Interview 1: The interview started with a basic introduction. Then the interviewer asked me the coding question. The question was to find the sum of two numbers represented by a linked list and reverse the answer. You can find a similar question here. 

• I first started to tell him my approach. I asked a lot of clarifying questions as well. 
• Once he was satisfied with my approach, he asked me to code it. I then wrote the code on Codechef IDE. 
• He then asked me to run it. There were some errors in the code. I resolved them. 
• He then gave me some test cases and asked me to run the code for those test cases as well. 
• He then asked me about the time complexity and space complexity of the approach. 
• He then asked me about constructors. He told me to write the code for copy constructors and explain it.
• After this, he asked me some subject questions as well.
  • What is encapsulation?
  • What is thrashing?
  • What is paging?
  • Difference between thread and process
  • Have you used Linux?
  • What is the command to update the GCC compiler in Linux
  • Why have you used MongoDB in your project?
  • Which sorting method is used by c++ in inbuilt sort?

This round lasted for around 1 hour and 20 minutes.

Round 3: Technical Interview 2: This round started with a basic introduction. 

• The interviewer then asked me to explain my project and asked some questions related to it. 
• He then asked me to write the code to find the nth Fibonacci number. I explained my approach and then wrote the code. He then asked me to run it. It ran properly without any errors. 
• He then gave me some test cases and told me to run the program. 
• The program ran for all of them. He then told me to run the program for input as 100. 
• The program was not able to give the correct output as this input is very large. 
• He then asked me to optimize it. He asked me how will you handle such large inputs if we need. I answered all his questions. 
• He then asked me if I have any questions for him. The interview ended in around 20 minutes.
