Recruiter phone call then hiring manager phone call. Given that both phone calls went very well, yet I get a rejection the next day, I believe Insulet did a reference check by reaching out to my current employer because they were both in health care, and there were some connections in common. This is absolutely not okay. If you need references, they will be provided upon request, and references should not be asked of an employee's current employer. What kind of reference did Insulet expect? This was unfortunate, as the company appeared to have a good mission, but I will now recommend prospective job candidates consider this experience if they choose to apply here.
