Envié una solicitud electrónica. El proceso duró 1 día. Acudí a una entrevista en HubSpot en may 2025
Entrevista
You have to start with a coding challenge. They do not accept any portfolio of previous work. I give the example of asking a nurse if they know how to put on a band-aid after working in the profession for years. I found a bug in their API that did not recognize that midnight starts a new day. No one was available to help resolve that bug, so I could not complete the test (I kept getting a message stating the response is incorrect). This turned out to be a massive waste of my time. The testing platform has a bug that caused my solution to be rejected. There was no means for me to get support around that issue. That is very telling about their culture.
Preguntas de entrevista [1]
Pregunta 1
I was asked to call an API to get phone call data and basically group it by day. I then had to post that data back to the API. After multiple attempts, I could never get it to tell me it was correct. I spent half the allotted time before concluding that, the API does not count midnight as a new day.

Entrevista
I went through several rounds, including an initial screening, a technical assessment, and follow-up interviews. The process was well structured, but I found the technical part challenging because it required both problem-solving and clear communication under time pressure. The interviewers were professional, and the questions were relevant to the role. Although I did not receive an offer, the experience was still valuable and helped me understand the company’s expectations better.
Coding assessment with multiple levels. levels open up as you pass them. Time constraints looked tight. I could not get through all levels. It was related to Designing banking system.

Entrevista
Consists of an Online Assessment, followed by 3 rounds (2 System Design, 1 coding)
One of the System Design interviewer was less experienced (with an experienced shadow interviewer). I feel like they didn't drive it correctly, didn't ask me the right follow-up questions and eventually gave negative feedback.
