Why sigh? Spell check is free and ubiquitous in this day and age. If someone is writing to a potential employer and overlooks that squiggly red line telling them something is potentially wrong, why should I believe they won't also misspell a variable, use = instead of ==, or overlook important compiler warnings?

Not to mention this example is in your face. For most attention to detail issues there isn't an obvious red squiggly - instead you actually have to pay attention to detail.
