consider (someone) for (something)
To contemplate giving something (often a particular job or role) to someone. I considered Walt for the promotion, but his constant lateness soon made me question that decision. Which actresses are you considering for the lead?
consider someone (as) something
to think of a person as a particular type of person. I don't consider you as a possible candidate. I consider myself an excellent cook.
consider someone for something
to think about offering someone a job, office, or other responsibility. Would you consider David for the job? I could not possibly consider you for the position.
