I am not one bit suprised to hear they would mention no tats. I do not have one myself, nor am I offened my anyone else having one. I understand the reasons, but do not agree with them.
This all stems from each individual's perspective on what is right and wrong. Companies keep things neutral, to prevent others from being offended.
I could mention that I have gone to many interviews, and if I thought for a moment that I was not hired based on what they see then my skills (that would show what I can bring to the table) were a second priority.
I have been growing my hair long for many decades. When I cut it about every 2-3 years, it is not short for long. Majority of the time it is pulled back, and when I am in nice clothes-only a single hair tie. The longest it has been was the small of my back. There are many who would rather judge for what they see, then to ask about it. These individuals is the reason why companies keep in neutral.
I grow my hair to donate to locks of love, for cancer kids to have a wig to wear. Trust me when I say, there is NO negative words that could ever be said to cancel even one smile that I have seen over the last 25+ years I have been doing this.
