About The Hiring Process
We are keen to explore your resume and, if you would like to, a cover letter with some of the things that drive you, professionally and personally as well. Let us know what makes you excited regarding your future role as a Software Engineer at AREX!
If it seems that we are a good fit for each other, we will set a call! The goal is to explain more details related to the team, tech stack, the duties of the role you are applying for and, more than anything else, get the chance to hear about your trajectory. This should take half an hour.
Next we will share a technical challenge that is expected to be completed within one (1) week. You will get a thoughtful description of the expectations in terms of tech deliverables and the way those will be submitted.
We'll let you know how things went within a week! If it still seems like a good fit all around, we'll schedule a one hour meeting with two of your peers to deep dive into the solution, so you will be able to explain what was achieved, the techniques you applied and trade-offs that were made.
Last but not least, you will get a call from one of our product savvy teammates for a half an hour conversation regarding communication, collaboration and customer focused design techniques.
At this point, you will get an offer letter! If not, we will let you know at any stage of the process, so you aren't left hanging.
Not sure if you'd be the right fit? Apply anyway! We'd love to know more about you and have an open conversation in respect to how we can grow together.
