Initial Interview with a Talent Manager
This initial meeting is focused on overall communication and personality fit for the UpStack network. We look at how you present yourself, how prompt you are for the start of the meeting, your internet connection and other remote working essentials. 

 We recommend taking this initial meeting as serious as an interview, due to the fact that when we check personality traits, we look at them in the same way our clients would. After the introductory meeting, if it has been successful, you will be invited to a coding interview.

The Coding Challenge

One of our senior developers will lead this meeting and it will focus on the specific skills of the job you are applying for. Expect to screen share and code in real time, along with other fun stuff and it will last for no more than 1-3 hours.

This involves a few tasks to resolve in real time (live coding and screen sharing ) with one of our senior engineers on your technology. You will be given the assignment, and then left to work on it, once you are completed the interviewer will analyse your work, and report back to the HR department.

Feedback and your UpStack Profile

You will receive a feedback from us no matter the answer.

If the answer is “Yes”,  you will be notified within a few days and the process of sending an offer and creating your profile will begin.

If your profile is not quite what we expect for the moment we will keep in touch for future collaborations.

Your UpStack profile

After you have accepted our offer and have signed the contract, it is now time to create your UpStack Developer Profile. 

Your profile (which is very similar to a LinkedIn profile) helps us to keep all your information in one place, match you with projects and present you to prospective clients.
