I don’t have any med-tech industry experience but I imagine the design review experience being tense for the product developing team. Passing a design review means completing a major milestone in the project development process and shows that the product is ready to be launched therefore it can be distressful for any engineer/developer. The environment of the meeting can vary depending on your experience in the company and with similar projects, the design review board might be more critical and scrutinous of a project with team members new to the company or new to the type of project but would be more understanding towards mistakes while seasoned employees may be given some slack but mistakes might be treated harshly. It can also vary depending on your popularity, if you are generally well-liked or the company wants to see you succeed the may be more nurturing and forgiving of mistakes, if you are not popular there may be ill intent during the review. It can also very with your professionalism and readiness during the review (this you can definitely control). It can also vary with how dynamic/creative versus traditional the company will be. There are a lot of variable that can dictate the design review meeting culture.
