It seems that many are worried over tattoo/marks/scars etc on their body and arms.
Just don't be lazy and start reading...
Here's my solution:
If you have tattoo/marks/scars etc on your body or/and arms, look in the mirror and see where is it located exactly. Then, imagine you wearing the uniform. And see for yourself, whether or not can it be seen. Of course most of you know how the uniform looks like?
If you don't, attachment is there. - I can only find a few airlines that have clearer pictures, if you have others, please upload.
If you still don't search on the internet or go to the airport and look out for the crews.
Be frank to yourself, I am sure you don't want to make a fool out of yourself by just blindly go for the interview knowing that you have tattoo/marks/scars etc on your body.
Always remember to be frank to yourself. Never lie to yourself over your own weakness.
If you have a small scars or/and marks, try conceal it and see for yourself whether can it still be conceal?
Tip: Try sally hansen leg spray. It can be used as a good concealer on any parts of your body. - Just in case some of you might ask where to get and how does it look like?
