Applied externally through LinkedIn/Glassdoor.

Received a coding challenge that comprised of three questions (time limit: 3 hours).

• The first involved basic API calls.
• The second was a dynamic programming question.
• The third was about implementing functions in React, given some boilerplate code. I definitely needed the 3 hours for polishing up the last question.

A week later, I was notified that I was moving on.

The online interview consisted of technical JavaScript questions and general inquiries about my background/resume.

After this step, there was no communication for about 3 weeks, so I assumed I did not get the position.

I got a phone call, about a month after my online interview, saying I received an offer.

What is a Promise in JavaScript?

Could you give me an example of when using Promises can be ineffective or inefficient?
