HubSpot Software Developer interview questions

Overall I found the whole process very impersonal and chaotic, leaving me with not the best impression of the company. I accepted another offer before getting the results of my interviews with HubSpot so I don't know if they would have extended me an offer. Summary of the process: - Recruiter contacted me on LinkedIn, initial 30-min call. - Passed the 3-hour take-home test and received automated "congrats" email saying they would be in touch soon to schedule interviews. Then received email from recruiter saying sorry, but I didn't pass the take-home test. I emailed back pointing out the mistake and she said "oops", the rejection email was meant for someone else. Yikes... - A few weeks later: live coding interview and live system design interview, both starting with behavioral questions - After the tech interviews I was scheduled to have a debrief with a different recruiter who I hadn't met yet. She didn't show up. The coordinator apologized that he hadn't seen a conflict in her calendar. Over the next few days, we weren't able to find a time that worked for both of us so we just never connected over the phone - A few days after tech interviews I accepted an offer from another company. I emailed the HubSpot recruiter to let her know that I would be dropping out of the process. Received no response. - A few weeks after my last email to HubSpot I get an automated email asking to fill out a survey about my candidate experience. Other than that, no indication that they had even read my email.
