Need to hire someone

[NotAllThere]

Technical interview question #1:

You have a tree data structure that you need process, doing something different with each leaf in turn, and collating the results into another parallel tree. How would you go about that?

I'd probably program it in some way - go through a few design patterns to see which would fit best. Or do you want a less high-level answer? Do I really need to talk about traversing a tree?

[oracleslave]

Yes, a better line of questioning is something like:

We have alot of data in our business represented by tree like structures.

Have you dealt with data like this before?
If so, how was it represented and processed?
What are the ways of storing and querying tree data?
What are the ways of traversing and copying data in tree structures?
What are the trade-offs in speed and data storage for various implementations you can think of?
How might you represent a tree structure in a database, object model and flat file?
What if only leaf nodes be represented , how might you optimise the data structure in this case?

The principles of the above are almost exactly the process I follow with some minor curveballs thrown in.

For 500 PD rate you want someone who can... list all the GOF patterns..

I hope that was sarcasm. The ability to list all the GOF patterns but unable to sensibly apply them is a Bob characteristic.

It's 50p and it's not worth drinking...

not true here, Bean to cup and quite bearable.

Hire me!

I’m not a one-trick pony. I’m not a ten-trick pony. I’ve got a field of ponies waiting to literally run towards this!

When I need someone to deck a senior manager your first in the queue. Otherwise....

DimPrawn, the brand.
