The resume can say “fluent.” The first phone call finds out.

Claims are cheap on paper and expensive in the room. Inflating what you can do buys a short window and then hands you a moment where the gap becomes visible to someone whose opinion matters. The strange part is that honest limits rarely cost you the chance, since people choose for trust and trajectory more often than for a finished skill.

Look at how you describe yourself and find the one line you would rather not be tested on. Either shrink the claim to the truth or spend this week making the claim true. Both work. Only pretending comes with a bill attached.
