Phone screen coder pad interview.

4 stage question.

Had a complete optimal solution with all stages answered and all test cases passing. Verbally communicated my strategy and my thought process throughout. The interviewer agreed that everything worked correctly and it was optimal.

Two days later, a generic rejection email from the recruiter with no feedback. I asked for feedback and was ghosted.

I would not interview with them again. How a company treats candidates is a reflection of culture, and I don't want to be a part of Instacart.

4 stages:

1. Create a class that stores a value and gets a value.
2. Allow that class to store values with a timestamp.
3. Be able to retrieve the value at a specific timestamp when given a key with a timestamp.
4. If the timestamp doesn't exist, return the closest value to that timestamp along with the closest timestamp.
