How can i make a employer feel comfortable?

Question

I apply to mostly engineering jobs(and am mostly interviewed by male employers). So, the question goes to you. So, you meet a very a confident young, attractive guy, who is talented, knows what he is talking about, can get the job done, have an impressive resume. But it worries you that he may have more than one option. So, now, what is the best thing that can make u feel secure? ie, make u feel that you can secure the employee, by some action.
Obviously, if the prospective employee makes u feel that he has the final say in the job process, that is to say, he will choose who he likes, you dont want that. However, he gets u the message that you can some control over the process, but by basically letting u make a good offer or just going with an easy to deal with boss, even if the offer isnt good.
It is very clear that for u to take the next step, u have to feel that you, as an employer, can put some fight and secure the best employee, what is it? Real world experience appreciated!

Let me give some details as to why the employer is also under pressure.

Well, please note that this is not a walmart job. It's a job at an investment bank or some giant software company, or even a small startup company that is going somewhere. That is to say, the employer himself has to compete for his employees because some of them are extremely qualified and that can mean serious business. Like for example, they may be able to release a product in 1 year instead of 1 and half years or cut 10%-20% costs which is in hundreds of thousands to millions. Please understand this!

Ok, the prospective employee makes u feel that he is going to push you and your goals foward, esp. when these goals are hard to achieve or are expensive.

Answer 1

I would feel confident in hiring a highly qualified and ambitious employee only if that candidate could convince me that he wanted to work specifically for MY company for a reason, not just to get a job. I would want to see passion for the company's mission and goals, a desire to be part of the team (and a reason why) and a real understanding of past and potential future of the business.

While it is a competition to get the best employees, the best are not always the ones with the highest degrees, specific experience, or the brightest futures - the best employees (from an organizational standpoint) are the ones that are invested in the company and are interested in advancing the goals of the company as well as their own.
