Technical Account Manager

Being a woman in tech, I only recently started advocating for myself at work about advancement opportunities. Because of this I wanted to ask this question to my male counterparts. When you have 1:1's with your direct reports and talk about career growth / aspirations what is your managers’ response typically? I’d like to gauge how my experience (negative) differs from others. For instance are you met with blockades, enthusiasm, dread, etc?

  1. People Operations Specialist Interview

    Anonymous Employee in Denver, CO

    Negative Experience
    Average Interview

    I applied online. The process took 2 weeks. I interviewed at Castor (Denver, CO) in Dec. 2022


    Do not believe this companies job titles. This job was for a position that is responsible for the payroll for the entire United States. Literally. When I brought up in the interview the job title didn't match their answer was, "well there was a question that asked if you have payroll experience" I said I have experience with payroll, but it was not my responsibility to administer payroll for the entire company in an entire county. Good luck with this company. The first interview is someone in Europe and this makes it very difficult as there are strong language barriers that are difficult to overcome.

    They asked about experience. They asked where do you get updates on HR new and rules.
