Six hour interview at a large firm in a high rise, I have just finished my freshman year in undergrad as an EE, and it was the second real interview I have ever had in my life, the first one I had ever had was for a freshman engineering job, at a small software company, that had been casual and only taken 20 minutes.
I was interested in law, but that had only really seriously begun thinking about it around that time, so really didn't know much about it. I was also so nervous I am sure my face was fairly white the whole time.
To say the least, it didn't go well
Now that I am finished with engineering and am in law school, I've interviewed for engineering positions at least twenty times and at four firms for a IP law firms, that interview was easily
the most extreme interview experience I have been put through.
