How many Mondays and Fridays were you absent last year other than vacation or holidays?

The interviewer wants to know about your work attendance at your previous employer. If you were absent many Mondays or Fridays, it shows you like to extend your weekends and that you may be an unreliable employee. Be honest in your answer, as the interviewer can ask the same question of your previous employer when called for a reference. If you called off work many Mondays or Fridays, you might be passed over for the position unless you have a valid reason.
