• Experience with alternative clouds (AWS/GCP) in addition to Azure.

Don’t meet every requirement? 
Studies show that many qualified candidates, especially women and underrepresented groups may hesitate to apply unless they meet 100% of the criteria. If you meet around 50% of the requirements and are excited about this role, we strongly encourage you to apply. We value potential, learning ability, and diverse perspectives as much as direct experience.

Interview Integrity:

During the interview process, we're evaluating your individual problem-solving skills, creativity, and approach to challenges. While AI tools like ChatGPT, Claude, and Cursor are part of your daily toolkit once you join B-Yond, all interviews, assessments, and take-home assignments must be completed independently. 

You may not use AI tools, third-party services, coaching platforms, or content-farming services during any part of the interview process unless we explicitly permit it. We will clearly communicate when AI tools are allowed for specific assessments.

Any indication of third-party assistance or AI-generated responses will result in immediate disqualification.
