On their careers blog, Stryker does an excellent job of outlining their entire recruitment process and timelines that every candidate can expect throughout the process. If you get to the point where you are offered the job there and sign your formal offer letter, one of the next steps that gets kicked off is a full background check process. Depending on the role you are being interviewed for and potential clearance with hospitals and clinics, the background check process can be thorough and include a pre-employement drug screen. Your interviewer makes you aware of this process to ensure that you will be willing to consent to all background and drug screening processes that Stryker has in place. Answer honestly and be sure to disclose anything that would appear on a background check at this point in the process.
