The hiring process started with a 45-60 minute phone screen. This screen focused on my background, OOPs, and C++ coding and design fundamentals.

Two days after my phone screen, I was offered an invitation to visit Fargo for an in-person interview. Ten days later, I was flying for an all-paid trip to Fargo.

My in-person interview started with a meeting with HR at 9:30 AM and ended at 5:00 PM. In total, I had 6+ interviews. I was tested on my basic computer science fundamentals: algorithms, software design, and testing.

Some of the questions asked were:

1. Given a function to read a file, write a function to find the number of matches for a given key in the file.
2. Reverse an integer and write test cases.
3. Shuffle a deck of cards given a random number generator that produces numbers with equal probability. How would you test that the random generator is random and generates numbers with equal probability?
4. Exception handling and testing scenarios.
5. Find the error in the given code.
6. Write a function that takes a word and returns the number of anagrams in a given file. Also, print all anagrams for a given key.
7. Test a given class, polymorphism concepts, virtual functions, and class design.

Reverse an integer.

Find the number of anagrams of a given word in the given text file, also print them.
