Ericsson R&D Interview Questions for Python Backend Developer Lead

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.
