Logitech Principal Embedded Software Engineer interview questions

I came across an interesting opening at Logitech and pinged couple of recruiters via LinkedIn. It took a month (!?) of constant prodding (including pinging the global head of talent acquisition) before I got a response from one of the recruiters. We setup a time to go through the job reqs. I have around 16 years of experience in what they are looking for, so I was confident this was gonna move fast. How wrong I was!! After talking to the recruiter, I was back in the "constant prodding" state..finally, nearly after 3 weeks I got a request from one of the directors for a quick phone call. Whew! My discussion with the director went well. He was looking for exactly what I was bringing to the table. He finished the talk with "Well, glad to see a fit from both the sides. Please look forward to the next steps from the recruiter". Now, after 2 weeks since that discussion, I haven't heard anything from the recruiter. I pinged the director and the recruiter, no replies. In the mean time, I was talking to other companies and got 3 offers. I have accepted one and will be joining them soon. Would it hurt to reply saying a "no", if they didn't think this was a match? Part of me wants to keep up this "constant prodding", to see when, if at all, I get a reply :) Will update more if I decide to do that.
