Hiring Process

When applying, we acknowledge and encourage that you use AI to refine your resume. We look at each application and would encourage you to include only relevant information and to the point. When mentioning skills, indicate the ones which you only have a familiarity with as opposed to extensive experience. A cover letter is a plus even though not strictly required. Please refrain from using AI for the cover letter if you do include one.
Our process focuses on understanding your approach to problem solving and includes both ideating about a real world challenge and a take home code challenge. We will ask you to solve real problems which may be related to our product and context at Heartbeat Medical. The challenge is crafted to be meaningful and specific – while just like in the real world, you’re welcome to use AI tools, it’s designed to test your unique approach and reasoning, and not a definite end result/output.
As part of the process, especially if you are in Berlin, you’ll also meet with members of our team in technical and non-technical interviews to get a sense of what working together will be like.

We are looking forward to your application!
