The initial recruiter call was easy to set up via an automated system and felt friendly and conversational. I got feedback at the end and was asked to set up a call with the hiring manager. The hiring manager was open about the role's challenges and promised feedback within 2 days. A week later, HR asked for examples of my previous work, which is unusual for media roles. I declined due to confidentiality and suggested a case study instead, but then got ghosted. After chasing HR and the hiring manager, I got a generic rejection. I followed up again for the promised feedback but received no reply.

Behavioral Technical Presentation
I had one initial screening call, and then went through 4 more interviews. These were with the hiring manager, their boss, a key person for the role, and the senior director for HR in EMEA. The last one was really urgent and they needed it done during my vacation time. After these five talks, they said the hiring manager was happy to move forward with an offer and I should hear soon. It's been over two weeks and nothing, then the recruiter got in touch to say the role was gone and they weren't proceeding. This is the second time this has happened to me with Dexcom. I feel really disrespected, especially since someone from HR leadership must have known this before interviewing me.

Technical Behavioral
The first interview was a technical one with the hiring manager. He was really nice and we had a smooth conversation where I explained my role and my two most recent work experiences from my resume. Since the department is IT/OT, he was particularly interested in my integration testing experiences and my use of the V-model for testing.

Behavioral Technical
The whole process was a nightmare. I had an initial chat with HR who was quite good and went over the role and my background. They mentioned the hiring manager was away for two weeks and they'd get back to me. After the two weeks passed, HR contacted me with some dates for an interview, and we set one up. I took the day off using annual leave to get ready for it. I logged into the Teams meeting 15 minutes early to sort out any tech issues. Ten minutes after the interview was supposed to start, nobody else had joined, and I thought I had the wrong time. I checked my email and found one sent just 10 minutes before the interview saying it was postponed to later that week. No call, just an email. I felt this was really disrespectful, especially since I'd used my own leave for it. Given how I was treated, I decided to withdraw my application. Interviews are meant to be a two-way street, and first impressions matter. It felt like a waste of my time and annual leave. A simple phone call would have made all the difference. I guess it's a lesson learned about how they operate, and I wouldn't consider applying there again.

- The initial HR interview was very straightforward, mainly focusing on your past experience and the company.
