InfoEdge conducted a virtual recruitment drive for the role of Software Engineer along with a 6-month internship. Around 60 students were eligible for Round 1.

Round 1: Online Assessment (94 minutes)

• Consisted of coding and MCQs.
• MCQ Sections (6 MCQs in 6 minutes each): Linux Environment, Cyber Security, SQL, Data Structures.
• Coding Questions:
  1. Expression Evaluation (stack-based).
  2. Remove k different types of items from an array to minimize the resulting count (Medium level, 25 min). This can be solved by finding frequencies, sorting, and removing k largest frequencies.
• 10 students who solved both coding questions moved to Round 2. Interviews were scheduled the next day.

Round 2: Technical Interview 1

• Started with self-introduction.
• Discussion on projects and previous internships.
• Coding Questions:
  1. Find elements present in the first array and not in the second. Solved using a Hash Set.
  2. Longest Palindromic Substring. Explained brute force orally, then wrote optimized O(n^2) time and O(n^2) space complexity code.
• This round lasted around 40 minutes.

Round 3: Technical Interview 2

• Started with self-introduction.
• Coding Question: Minimum number of distinct elements after removing m items. The candidate explained the approach (using a frequency map or sorting).
• This round lasted around 30 minutes.

Round 4: Technical Interview 3

• Started with self-introduction.
• Coding Question: Expression Evaluation (stack-based). The candidate explained the logic in detail, but faced a runtime error during compilation. The interviewer seemed satisfied with the detailed explanation of the logic and example.
• This round lasted around 40 minutes.
