HubSpot Senior Software, Engineer Frontend interview questions

I applied for Hubspot towards the end of May, within a week I get an email to arrange a recruiter call (which was about 30 mins). The recruiter sends me the 1st take-home exercise which I submitted within a week. The take-home exercise is very straightforward. It needs some basic knowledge of data structures and how to consume an API. After 3-4 weeks of waiting, they tell me that I aced the exercise but that they're evaluating their H2 hiring and that they'd reach out in 1 week to proceed with the next interview. Since then 5 more weeks went by and they have completely ghosted me. I've reached out and got no answer. That's no way to treat a candidate, you should at least let them know you have a hiring freeze (if that's the case?) .

Initial phone screen, then a 3 hour take home coding challenge. If successful you'll schedule the interviews with the recruiter. I had 4 one hour long rounds of interviews. 2 live coding interviews (Javascript), 1 with the hiring manager (behavioral questions), 1 system design interview.
