It depends on how you look; who hired you and who you replaced!
If you look good, expect a warm and friendly welcome. Depending on your gender, you will get the appropriate treatment from the opposite gender employees.
If you are abnormally good looking compared to the other employees of the same gender, watch your back!
If you are hired with the blessings of higher management, expect a good first day. If not, watch your back!
Finally, if you are replacing someone who had many friends but was fired because of your immediate boss, again, watch your back!
