Was selected as an intern from college.

The intern selection process included a written round with C and Data Structures questions, one test case question, and one coding question. The exam was administered offline via pen and paper.

Based on the exam, 19 candidates were shortlisted. After 3-4 rounds of interviews for each candidate, 5 were selected.

Following a 2-month internship, three rounds of interviews were conducted for a full-time offer.

The interviews were fairly moderate.

The interviewers were cool.

1. Given an array where one number is unique and all other numbers appear twice, find the unique number.

2. A question on the implementation of atoi.

3. Clone a linked list where every node has two pointers: one points to the next node, and the other points to any random node.

4. Reverse a doubly linked list of length k in chunks.

5. Design a system to maintain the 10 most frequently typed words in the current document in MS Word at any given time.
