Yes, we should realize that employers are bosses, and because they are paying our salaries, don't deserve to be cheated by us providing mis or non-information for our own selfish reasons, viz to get a job. Tell them everything that might prevent you from being chosen for the job, eg tell them you smoke or drink or anything else that they may not like about you so that they can avoid potential problems down the line after having employed you.
Believe in yourself and fairness in the world. Trust employers to make the right decisions re recruitment 100 % of the time. Bare your souls to them, and, for God's sake, don't tell them lies, even white ones!
We should make life as easy as poosible for them - they are the kingpins, the special ones. By contrast, we are mere serfs, black or white or of mixed ethnicity, whatever. Employers are perfect. but we are not!
