The process took about two weeks from the screening call to the offer.

• Screening call with a company recruiter to talk about the company, goals, and expectations.
• Online HackerRank challenge. If I understand correctly, it's always something from String Manipulation algorithms.
• Onsite interview (virtual because of the COVID situation).

The onsite interview included five sections:

• Another coding challenge on HackerRank (also string manipulation for me).
• Talk with the engineering manager.
• System design.
• Code review.
• Deep dive into your past experience.

Overall, it was a nice experience: interesting format, interesting, technology-agnostic questions, and friendly interviewers.

Write 3 functions that take 2 strings as arguments and return True if the strings match:

• Simple substring search: This function will check if one string is a substring of another.

• Wildcard character for exactly one symbol: Add a wildcard character that matches exactly one of any symbol.

• Wildcard character for zero or one of the previous symbol: Add a wildcard character that matches zero or one of the previous symbol (e.g., a* means either an empty string or 'a').
