Hi there
Try out places like Lowes and or Target. They hire for the holiday season and too, they like part-time workers. I think since you owned your own salon, you want to stress that you know how to deal with the public REALLY WELL. Also, as you mentioned, you are willing to work weekends and nights.
Try to keep in mind when interviewing that it's nothing personal.. You never know what's going thru a possible employer's mind.. could be someone in the group had on a shirt they liked or said something that resonated with the employer more than anyone else. it's really sometimes as simple as that. Also, I don't think as many people do this anymore, but no matter what type of job you are applying for.. DO send a thank you note and indicate how great it was to talk with them and IF you are interested, do reiterate as such.. So often , people don't extend common courtesy anymore. Even if you don't want the job... hey, one job can lead to another.
I once interviewed for a job but the guy didn't think I was quite right for what he was looking for, however, he did refer me to another and BAM.. I did land that job.. so you never know.
It does seem these days especially that you have to interview more often than not.. and too, you might think, what is wrong with me.. again, its not you.. My husband who has a great deal of experience from the brokerage industry to running two of his own businesses had to interview all over the place until he finally got a job. At first, he did wonder.. hey is it me... but eventually, you do toughen up and realize that it's probably not you. There were times when we thought he was the perfect candidate and then.. no he didn't get the job.. but you will land a job.. try to keep smiling.. In my opinion, you have GREAT experience, perhaps it's just how you are selling that experience? in some cases, you might seem over-qualified. therefore, if you are looking for entry-level, could be you have to help the employer wrap their mind around why you would be a good hire.
I wish you the best.. btw, 32 is VERY young :)
