Job Interview

Ok, job interview on Monday.

Now problem is, i always freeze up in interviews. In my head i know what i am going to say, but when i go to say it, it comes out comepletley different.

And even worse, when asked specific tech questions, i completey blank.

I feel like such an idiot during the interview and beat myself up for it.

Now having said that, i’ve not exactly wanted for a job lately, someone always seems to think i’m worth it, no matter how much of a simpleton i come across as.

Any ideas on how to relax and not look like i should be wearing a hockey helmet?
And how not to freeze up on tech stuff?
