Klaviyo Sr. Software Engineer interview questions

I had never heard of Klaviyo until they contacted me through a job search platform where I had posted my profile and resume. My first conversation was a phone call with an internal recruiter who was extremely aggressive and using ridiculous "negging" tactics. He made a point of denigrating several items on my resume and demanding I give him more so he could "sell" me to the hiring manager - dude, YOU contacted ME! Eventually I got scheduled for a "real" technical interview. The engineer I had a video call with seemed competent, but with a thinly veiled disdain. Not sure if he was having a bad day, but it was obvious he would not want me to go on the next round. The only good thing that came out of Klaviyo for me was better ammunition for interviewing with other companies, how to spot red flags, etc.
