When you go on your job interview（面试）,be sure to dress well, be on time, do your research and NEVER ask any of the following questions :
1．" How quickly could I be promoted（晋升）?"
An employer first of all wants an employee to be happy with the position they have. Ambition（抱负） is good, but there is a time and place to discuss promotion, and it ' s not during an interview.
2．"Will I be able to work from home?"
This is basically telling your future boss－before you've even started－that you're too lazy to come into the office.
3．"How much vacation time does this position offer?"
Although this could be asked, this is the type of information you should get AFTER you've been offered a position and not before.
4．"Will I have to work with a team?"
Almost all jobs need some kind of teamwork, so any sign that you are not a good team player will leave you with unfavorable points in an employer's eyes.
5．"Does this position come with a handsome pay?"
The pay is usually discussed after a position has been offered. If an employer offers this subject, feel free to discuss it. Otherwise, try not to look like you are interested only in things for your own good. An employer will more readily hire someone interested in bettering themselves AND the company as a whole.
When can you offer the subject of pay?（ ）
事实细节题。由最后一段第一句话可知，薪水问题通常应在确定自己得到这份工作后再讨论。故B正确。
