I'll disagree with ChrisF, there's nothing particularly offensive about those comments. Although, in the way they're shortened by OP, they do sound kinda rude.
First one is just an opinion, although expressed in not exactly kind manner:
Honestly, if you don't know the answers to these questions you aren't ready to work as a professional software developer. This is beginner level stuff.
Sauron, It may sound insulting to you now, but trust me, when in five-ten years you become pro and new intern comes asking the same question, you'll have the same reaction (although you may be wiser not to speak it out like that).
The second comment has nothing to do with you at all. It seems to me, that it refers to the state of the industry in general (to the kind of interview questions other companies use).
...Is this how other companies interview? Is this why we can't find anybody suitable to hire?
Overall, I would suggest being kind to people even when they're not so kind. Everyone has bad days.
Let the one who never left tongue-in-cheek comment to some silly question,
throw the first stone cast the first downvote.
PS The post itself, for the reference
1) Since Shog9 promised to flag such 'not useful' comments when he sees them, I've found some. By Shog9 himself.
What is the best way of storing time?
ActionScript vs C#?
How legal is screen scraping?
Shog9, I'm absolutely serious, I do expect to see these comments on the 'recently flagged' page.
The first post also has a tongue-in-cheek comment by Michael Myers. I think, we should strip him from his moderator privileges now.
I was absolutely serious asking this: Every time when you grumble, do other people grab you, drag you to the nearest tree and lynch you? If not, why are you doing this to other people?
