The subject is been specific to the role of management, so I don't gender should be a problem. Had it been it's a job where specialization is needed but this management and what matters in role of management is qualifications. You can give the role of a management to a man that doesn't have experience and would fail you woefully and you can also employ a woman who doesn't have any form of experience do a very job. Likewise, you can employ someone a male of female that are both qualified for the job and will deliver the job accurately.

You want to employ someone, you want to look at the post experience and where they have, recommendations letter is not needed as that can be manipulated, you need to check down the role they have played and their past place of work if the company is progressing or not, you need to check their resume, you need to also put them on some test and make sure upon acceptance of the job, there is expectancy from them perhaps some revenue that must be attained before they can finally be accepted fully, this will even give them pressure and enable you know if then can work in a tight position. I think this is enough to know if you have hired the right candidate.
