I botched another interview today.
I had plenty of help and advice beforehand. I was well prepared. Even a mock interview at the job agency two days before with 'inside' questions.
But when it comes to the real thing. I freeze and forget what to say, don't read between the lines and don't understand what the questions really mean.
The people before me spent around 30min being interviewed. My interview was over in under 15min.
Walking under a bus is preferable to going through another interview with strangers from a HR department.
