Hi, I'm Alex — the person accountable for engineering hiring at Simprints. I'm sorry to hear that you never got a response to your pre-interview submission. We just finished reviewing a surge of submissions we received over the holidays and into the new year, so you should have received personalised feedback on your answers. We typically get two engineers to review each application, and have an average response time of around two weeks, but in your case it may have been 3 or even 4. In any case, if you still have questions, feel free to shoot me an email (alex@simprints.com) so I can look into your specific situation.
