I applied through a recruiter. I interviewed at Invisible Technologies in Feb 2025
Interview
Met with recruiter and then immediately had two technical interviews, one coding/leetcode, the next system architecture. I got rejected, and here's a snippet of the email verbatim:
However, after careful consideration, we’ve decided not to move forward. [INSERT FEEDBACK AS TO WHY NOT MOVING FORWARD].
I'm glad I wasn't given the opportunity to work for a company as careless as this one,
Interview questions [1]
Question 1
JSON manipulation leetcode problem; system architecture involving developing new REST APIs
I applied online. I interviewed at Invisible Technologies (New York, NY) in Feb 2026
Interview
Started with a recruiter screen, then another call with a tech lead, then a call with a principal engineer and then one with one of their operations leaders. I passed all of them and then they flew me to be interviewed by their client which is a large private equity firm in NYC. Up to this point they had signaled I was good for the position and they were excited to work with me. They had told me the NYC conversation would be mostly about fit but it turned into a system design interview.
Their customer did not want to hire me and therefore invisible did not hire me.
Be advised that they have not refunded me for my trip to NYC even after months of back and forth.
