Interview Process
The interview consisted of three rounds.
Round 1: Coding
The first round focused on arrays and hash maps.
- Two Sum
- Merge Intervals
- Hash Map Design
Round 2: System Design
We discussed how to design a scalable URL shortener.
Always clarify requirements before starting the design.
Example Code
def two_sum(nums, target):
seen = {}
for index, number in enumerate(nums):
complement = target - number
if complement in seen:
return [seen[complement], index]
seen[number] = index
return []
