The interview process involved a HackerRank coding exercise followed by an onsite interview. The setup for the interview was good; I was given an office tour and provided lunch.

Unfortunately, the interviewers were getting busy with other meetings, and substitutes were sent 30 minutes later. Some interviewers had a very thick accent, making it extremely difficult to understand the majority of what they said.

One other positive aspect was that, unlike most companies, they emailed the next day about their decision, which brought closure.

1. Design a system, like eBay, where third-party vendors can register their goods. While placing an order, ensure it reaches the supplier in real time.

2. Write code to execute a particular piece of code asynchronously and periodically.

3. Determine if a string is a palindrome.

4. Determine how many substrings are palindromes in a string. For example, in "aabbac", the palindromic substrings are: a, a, b, b, a, c, aa, abba, bb.
