I recently had an interview that I thought went very well. The manager that I interviewed with asked me to email him the following day with my salary requirements. We had not discussed salary or benefits at all, other than a passing mention of health coverage (he told me it was excellent). I was not offered the job at this time.
I carefully researched the position in question (one which I have previously held), considered my experience and skills, and presented an offer that I felt was a good starting point for negotiations. I expected that it was higher than they would be prepared to pay me, but I assumed they would be prepared to counter-offer if they were interested in hiring me. I also made sure to mention that we hadn't fully discussed benefits, to suggest that I was amenable to reducing the salary based on the benefits offered. I received an immediate reply saying that they were still interviewing and that they would get back to me.
It's been about a week with no reply (this is a small company, and the person I spoke to is directly responsible for this decision). I'm starting to question whether I inadvertently priced myself out of the job. All the questions I can find related to this subject say "Don't give salary range before interviewing" and "Give a higher number than what you're looking for once you've received an offer." I was unable to find best practices for a situation where I've already had the opportunity to sell myself, but haven't actually been offered the position.
In short: is it likely that I sabotaged myself either by supplying a hard salary number prior to any kind of job offer, or by deliberately offering a number higher than what I would consider acceptable?
I recognize that they still may not be done interviewing yet, and that they may choose someone else for entirely unrelated reasons; I'm only asking whether or not what I did would generally be considered appropriate for the situation.
