I applied online. The process took 2 months. I interviewed at HubSpot in Jul 2022
Interview
One of the best recruiting processes I've ever had. My recruiter was super friendly, organized, and provided me with plenty of detail throughout the whole process.
The process included:
1. Phone screen with recruiter
2. Take home assessment which included parsing some data from an API endpoint and sending it back
3. Onsite which consisted of 4-5 rounds. Mine were frontend system design, coding (easy leetcode), hiring manager behavioral, and javascript fundamentals.
Received super detailed feedback from the recruiter that although I did well in the javascript and behavioral, there were some gaps in my system design and I did not solve the leetcode problem fast enough. I really appreciated how much attention was put into the process and would definitely apply again later down the road!

Interview
Single exam no human interaction. The exam was like a college test, something completely unrelated to modern field work. Seemed a bit off base. Definitely didnt seem like a realistic approach to finding real humans to fit for a company.
