I was called for F2F after a brief call from HR.

I had three rounds of technical interviews, mainly based on coding on a laptop.

I didn't receive any feedback or reply, even after sending a reminder.

1. Given a string of integers and the value k, find the smallest integer that can be formed after removing k digits from the initial string.

2. Reverse a linked list.

3. Sort a linked list containing only 0s, 1s, and 2s without updating the data value in the node.

4. Find the 10th smallest number in an array of integers for large inputs.

5. Find the frequency of words in multiple files using multithreading.

6. Find the triplets in the array such that a + b + c equals zero.

7. Data structure used to implement hash_map and map in C++ STLs.
