The complete process involved five rounds including three technical interviews, one hiring manager, and one HR discussion interview round.

The hiring was for the senior technical lead job profile for a backend developer in Banglore, India.

All these interviews were carried out virtually.

Interview Coding Round

After having introductions, the Interviewer asked me a couple of coding questions. Here are those questions as I remember.

Question 1: Write a program to check if the two strings are anagrams or not.

Solution:

• Python program
• C program

Question 2: How to check palindrome string?

Question 3: Write a program to find the longest palindrome substring.

Note: While providing solutions or writing code to solve these problems, also discuss them with the interviewer.

After this, I got a call as I was selected for the second technical round.

Technical Interview Questions

This is the complete technical interview round.

Here are some of the questions I’m able to recollect now.

• Describe your current project and also tell me your contribution to the project.
• Then there were some questions related to the project that I was working on in my previous companies.
• Why do you centralize the database?
  Answer: You can describe the advantages of having a centralized database system. Just like, with a single snapshot, we can take a backup of the entire application data.
• What is SAAS?
  Answer: SAAS is the abbreviation for Software as a Service. Explain it with an example.
• Design an SAAS application to show the details over the map and in a tabular format.
• Then he asked me DB queries to filter entries.
  Answer: It is not expected you should write executable queries. Just tell him the approach.

Finally, I got selected and joined as Senior Technical Lead in Banglore.
