I had an initial phone interview with a HR guy (a recruiter from that company; let's call him "Bob") from a company that I was interested in. It went well, so Bob and I agreed that he'd send me a few time options for a 2nd phone interview with a more senior HR guy. (Company is in a different state, so everything is via phone/skype until later stages).
Instead of sending a few time options, Bob just sent me a Google Cal invite for a specific time. I didn't make a big deal since that time happened to work out for me.
A day and half before the specified time, I realized we hadn't discussed travel enough, since jobs which require traveling are an immediate "no" for me. I sent Bob a quick email asking him if this job requires travel.
Bob didn't reply, so I figured I'll just ask the more senior fellow during our phone conversation. The arranged time came and no one called me. (We had arranged that they would call my number, rather than me call them.) After about 10 minutes, I sent an email to both HR guys asking if they're still available to talk. This was around lunchtime. The senior HR guy never replied in any form, and Bob only replied at 6pm that day. Bob's reply was that he left me a voicemail and also tried calling again later in the afternoon to discuss the travel, but I hadn't picked up. Bob suggested that we touch base the following week.
However, I didn't have any missed calls or messages from him. I replied to him, trying to keep it positive, saying that I didn't see any missed calls or messages, and could he check that he called the right number for my cell - XXX-XXX-XXXX?
Bob replied that he did indeed call that number. Apparently he doesn't believe me that I didn't get his calls/messages. But from my side, he had called me on that same number for my initial phone interview, so I find this whole thing a bit fishy.
Either way, now he wants to reconnect to continue our discussions.
I'm not interested anymore, though, thanks to his communication (or lack thereof). I also highly suspect he was going to try to talk me into agreeing to a minimal amount of travel occasionally (even though I haven't heard a solid confirmation that travel is required). Again, I'm not interested in having that type of conversation.
What's a nice, diplomatic way to end this without burning bridges or making myself look bad?
