I aced my interviews but still did not get an offer. They are interviewing just for the sake of showing the world that they are hiring. I am pretty sure they are not hiring. The job I applied to was reposted on LinkedIn before I finished my interviews. I was well prepared for the interviews, I have worked on low-latency distributed systems at FAANG for 5+ years. I was interviewing at Hubspot just to practice my system design skills. I was well aware that Hubspot could not match my TC. They still rejected me saying the bar is really "high". The bar at Hubspot is pretty low. They have been asking the same system design and coding questions in the last 3 years.
