TBH...u have to face it fearlessly....its all about keeping urself calm and make sure that your confidence is high!!there is no other thing to this,ita all about mentality,if u go forward with the intention that they will laugh,u will stutter!You wont stutter if u have a bold and confident mind!! I have no idea on interviews,because i am 14 only...Try saying that u have a stutter,once u get comfortable...move ur hands alot!!try to speak calmly and keep moving ur head when u speak!!u get the idea.I know its hard to control ur fear in interviews...But once u get confident and friendly with the interviewer...U can speak a bit fluent!!
