My Infosys Specialist Programmer Journey (HackWithInfy) – Assessment to Interview

I wanted to share my entire journey for the Infosys Specialist Programmer role through HackWithInfy, in case it helps someone preparing.

Registration

I registered for HackWithInfy through the placement cell at my university.

Online Assessment (OA)

The OA consisted of 3 coding questions.

• I was able to solve 2 questions completely and partially solve 1.
• A few weeks later, I received the shortlist email for the interview round.

Round 1 – Problem Solving (Offline Coding)

After about a month, the interview process started. The first round was an offline coding test conducted physically in front of interviewers.

• We were divided into groups of 5.
• We were given 2 coding problems on the Wingspan portal.
• We had to solve at least one problem completely.

Common topics included:

• Greedy
• Knapsack
• Dynamic Programming
• Trees
• Graphs
• Segment Trees
• Fenwick Trees

I managed to pass 14 out of 15 test cases (3 sample + 12 hidden).

Round 2 – Basic DSA / CS Concepts

This was a short DSA round to check basic problem-solving skills.

My questions:

• Climbing Stairs problem
• Swap two numbers without using a third variable
• Merge Sort

Other candidates were asked variations of:

• Fibonacci
• Longest Increasing Subsequence (LIS)
• Longest Common Subsequence (LCS)
• Other standard DSA problems

If you’ve cleared the OA, this round is usually straightforward.

Round 3 – HR + Technical Discussion (1:1)

This was a one-on-one interview, mostly focused on resume and fundamentals.

• The interviewer asked me to rate myself out of 5 on each skill mentioned in my resume.

• Then asked basic questions from:

  • OOPs
  • SQL
  • HTML/CSS

This round lasted around 20 minutes and was quite relaxed.

Conclusion

That was the end of my interview process. Overall, the experience was smooth and focused mainly on DSA + basics of CS.

Good luck to everyone preparing for HackWithInfy and Infosys Specialist Programmer!
