Senior Software Engineer Interview Experience - Boston, Massachusetts
Process
The interview process began with a short phone call with a recruiter, followed by a 30-minute phone call with a software manager.
Next, I was asked to come onsite for a 1-hour coding test and review. After that, there was a coding challenge to build a full-stack web application, with a preference for using Python and Django.
If this stage went well, the next step was an onsite interview lasting 5-6 hours.
I was ultimately rejected due to some imperfections in the coding challenge. According to the engineer who reviewed my code, I did not demonstrate sufficient proficiency in handling errors and exceptions, despite having try-except blocks in every piece of my code.
The recruiter gave me a short tour during my first onsite. It was evident that the company's employees are predominantly white, as suggested by the posts on the Benefits page. As a person of color, I would advise others in similar situations to avoid this company.

- 2.0ShhhhhhhSenior Software Engineer • Current EmployeeBoston, MAJanuary 7, 2025Pros: Some fun projects and some great coworkers.Cons: Leadership shutting down conversation about benefit cuts was the moment the culture died for me. People were having an open discussion in an off-topic channel, asking questions and sharing feelings about benefit cuts that had been shared in a poorly worded email two days before taking effect. None of the comments crossed the line or were in any way unprofessional. They were discussions about benefits and work conditions, but because there was a layer of negativity (as there would be with any TC cut) leadership got uncomfortable and went to people's managers to stop the conversation. Over my time here there have been a lot of decisions I disagreed with, but could live with and commit to. This is different; for the first time, I am ashamed to work here.
