Nick's guide to Excel / VBA Interview Questions
I have hosted hundreds of Excel / VBA interviews, and I can work out very quickly how good someone is.
The biggest blunder to make in an interview is to say something like: "Oh, that's easy, I can do that in 5 minutes with the compiler and help files"
Well, in my interview, you have no compiler and no help files, so don't ignore syntax, or rely too much on help files.
You wouldn't turn up to a French interview with a dictionary and translate every word now would you ?

Here are some Excel VBA interview questions I might ask you.. Add a comment if you think you have a good answer.

Diagonal
My mistake, I read it as a continuous diagonal. So we start from the other end.
Option Explicit
Sub Diagonal()
Dim i As Long
With ActiveSheet.UsedRange
i = Application.Min(.Rows.Count, .Columns.Count) + 1
End With
Do
i = i - 1
Loop Until Range("A1").Offset(i - 1, i - 1) <> ""
Cells(1, 1).Resize(i, i).Select
End Sub
Diagonal
closer, but still not bullet proof..
Diagonal
Sub Diagonal()
Dim iLast As Integer
iLast = 1
Do While Trim(Cells(iLast, iLast)) <> ""
iLast = iLast + 1
Loop
iLast = iLast - 1
Range(Cells(1, 1), Cells(iLast, iLast)).Select
End Sub
Diagonal
this won't always work
Could you please give an
Could you please give an example when this won't work ? (this is assuming A1 always in not empty and "space" is not being an "entry"). May be I didn't understand the requirement correctly.
diagonal
That'll give it away..

There are 2 cases that will break your code.
Maybe this is better: Public
Maybe this is better:
Public Sub Diagonal()
Dim lCnt As Long
lCnt = Sheet1.UsedRange.Columns.Count
Do While IsEmpty(Sheet1.Cells(lCnt, lCnt))
lCnt = lCnt - 1
Loop
Sheet1.Range("A1", Sheet1.Cells(lCnt, lCnt)).Select
End Sub
2. Calculation
Name as many ways as you can to make Excel calculate something.
Select a formula in the
Select a formula in the formula bar and press F9. this will calculate the formula but will not print it out in the cell
