HubSpot Sr Software Engineer interview questions

First round: Typical 30-minute chat with recruiter to make sure you're not a crazy person or a bad fit. Second round: At-home coding exercise. 3-hour time cap. Retrieve a set of raw data from a RESTful endpoint. Raw data represents client availability across different office locations. Parse and process that data to determine the time most clients are available per office to hold an event. Submit response to another RESTful endpoint. Third round: 4-hour on-site. First, tour around the office with the recruiter + general chit-chat. Next, technical interview involving JavaScript language specifics. Next, behavioral discussion with Director of Engineering. Next, technical interview testing JavaScript, CSS, and HTML. Next, technical interview with a more traditional technical interview problem. Last, recap with the recruiter. There was no white boarding. I was able to write real code on my own laptop.

Applied online, within 1-2 days got an answer from HR telling that they liked my CV and wanted to go forward with the process. Had a coding challenge at home, passed then had my personal interview. I liked a lot to be honest. In the office I had a chat with about 5-6 people, first with the Recruiter, second with two guys which asked me things related to architecture, third a SQL challenge (which I failed - honestly it's been at least 6 years I don't work with SQL, just NoSQL) and finally with a manager. Despite the SQL, which was the only remote challenge, (also the call was very bad and I couldn't hear the interviewers properly) I really liked the company and I think their hiring process is good, people seems to be very smart and they respond quickly when you submit questions/enquiries through e-mail. I recommend this company for everyone.
