I think natrips is right.
Since u received a call from recruitment dept. they have shown some guys partying (those who look like some sort of star wars freaks
)The joke is :-
once the company was recruiting some freshers. On the day of interview, there was party in the office. All the candidates were pleased and many of them joined. After joining they realised that actually the place sucked like anything and the working conditions were rally really bad.
Then the chairman told them that the day was recruitment day and that was our HR dept.
So never rely on HR department.
and use ur brains (subject to availability)...
