okay so I just did Stryker's online assessment for their new grad SWE rotation program and I cannot find any info about this anywhere so here is my data point.
Platform: HireVue with a coding component embedded. Not CoderPad, not LeetCode's platform. HireVue's coding environment is a little clunky, FYI.
Format: 2 coding problems, 75 minutes total. You set your own time split.
Difficulty: both problems were easy-to-medium. One was a standard array manipulation thing (sliding window vibe, no trick). The second was a tree problem but shallow, not the kind that requires you to know every tree traversal variant cold. Significantly easier than what Google or Meta would throw at a new grad.
Language options: Java, Python, C++, C#. I used Python. The grader checked correctness and I think style to some extent (they mentioned clean code in the recruiter call).
There was also a HireVue video section: 3 behavioral questions, 60 seconds each to answer on camera. Questions were things like "describe a time you had to adapt to a change in project requirements" and "what does quality mean to you in a professional context." That second one is very on-brand for Stryker.
After the OA I moved to a recruiter phone screen about 10 days later, so turnaround felt okay.
Honestly the OA wasn't the hard part. The behavioral round later was more stressful because Stryker's values (integrity, accountability, people focus, etc.) come up explicitly and you kind of need to know them and weave them into answers. Not in a fake corporate way, but they genuinely probe for alignment.
For new grads targeting Stryker: medium-level LeetCode prep is sufficient for the OA. Don't ignore the behavioral prep. And look up what "quality system" means in a medical device context, even just 20 minutes of reading, because it will come up.
