HubSpot Sr Software Engineer interview questions

I was contacted by a recruiter and after a quick talk about typical questions as "why HubSpot?", "why you want to leave your current position?", the recruiter sent me a code challenge. You decide when you want to do the code challenge, there's no pressure on a deadline to do it. This code challenge it's about consuming an API, receive a JSON , do some process with it using data structures and send a POST with the solution. You've 3 hours to do it and you can use the code language you want. I did it on time correctly and the recruiter came back to me to do a technical interview on site. They didn't have any resources or maybe they had more interviews but they proposed to make this interview in the following month. Unfortunately, due to Covid-19, the interview was via zoom. The technical interview is divided in 3 parts: - System Design: tinyUrl - Database: create a social media - Coding: nGram I felt some of the interviewers didn't have too many experience doing interviews because it was really difficult to understand what they were asking. I asked for some examples to understand the questions but the examples given weren't so good. I think they were more focused in follow the interviews guidelines they have in their company than trying to focus on the candidate they were interviewing. Despite that, I was able to go through and I felt I was doing good during all the interviews. There were no bad feedback during the process from the interviewers. Even, I asked after finishing each part if the answers given were correct and if there were other way to do it or to improve but apparently, I was doing good according to the feedback received during the interviews. My surprise came when the recruiter came back to me saying they couldn't make me an offer because I didn't reach the level. I asked for more feedback and the recruiter gave it to me very kindly. The feedback given was a bit contradictory. The feedback said I was able to solve all problems in all interviews but for example in the database part they wrote I didn't show too much knowledge about indexing and in the system design part they wrote that I showed good knowledge about indexing....... It seemed that they wrote some randoms things just to say No. In my opinion, I didn't learn too much from doing this interview and I feel I was rejected before even starting all this interviews because of the global situation with Covid-19. If you are not going to hire or put the level really really high because of the situation, please let the people know before starting a process of almost 2 months.

I would like to congratulate Hubspot team for their amazing recruiting process. The online code exercise is exciting and challenging at the the same time. It evaluates hands-on ability, experience and concepts all at the same time. There was a really nice panel of on-site interviewers in Dublin who made me feel comfortable to do my best. The recruiting team made me feel wanted all along. I would highly recommend taking part in this process as it is enjoyable and we can learn a lot from it. Would also encourage preparation as it will help on the day and pay off in the end.
