I applied online. I interviewed at Vertex (King of Prussia, PA) in Aug 2017
Interview
I applied to a company called Entech who was working with Vertex. It took about 2 weeks before I was cut off. There building was very nice and it had a young friendly environment.
Two technical interviews, neither of them leetcode-y. First one focused on general problem solving (working through a problem scenario orally) second focused on questions about programming languages / OO concepts.
I applied online. I interviewed at Vertex (Philadelphia, PA)
Interview
They asked typical behavioral questions. Recruiter was very nice and conversational. Explained next steps very well and broke things down in great detail. Was receptive to questions from my end.
I applied through a recruiter. The process took 4 weeks. I interviewed at Vertex in Mar 2024
Interview
Initial phone interview with recruiter, then an online assessment (took a couple hours), then 2 1-hour back to back interviews, one being semi technical. I asked the interviewers about the absurdity of the back to back nature and they seemed confused too lol
Interview questions [1]
Question 1
Without being too specific (and not sharing any aspects of the assessment), they asked some basic programming knowledge.
