If my writing sample was not double spaced when I wrote it, should I double space it for my OCI interviews, or leave it the space it was before (1.15 spacing)?
Whatever makes it easier to read. Double spaced probably.
Shoot for 5-10 pages at maximum readability. Over 10 is no bueno.
Agree with both of the above two posters: readability is the priority. Double spaced is standard, but 1.5 is probably fine. Would not go below that (and would go more than 1.15). But, as said, don’t go over 10 pages. Chop it down if so.
Do writing samples need to be printed on resume paper?
Be pretty fucking weird to submit them on normal paper under a resume on resume paper. That’s kinda a dumb reason, but I think it’s right.
