<p>Actually i also had gone in a semi-formal attire. And i had wore clean jeans and shoes to make myself look more smart. But when i reached there i saw that the interview took place through the glass and they could view me only upto my chest. Let alone my pants or shoes, they couldn’t even see my whole shirt ha ha. Everybody goes in casual wear. One guy was in slippers. And that is not an exaggeration. He really was in slippers and looked like he had just got out of bed and directly came to the interview, lol. Dont worry. A clean simple shirt ot tshirt will do the trick.</p>
