How many times have you officially stood in front of the recruiting teams and formally handed them a resume?
Does it hurt? No. Does it help? Yes. How much? They don't say.
There's plenty of people who've been hired who've said "I went to X(3,4,5,6)" job fairs. Highest I heard was 17. Sounds crazy. At a major now, ink still wet on his CA upgrade when he got hired. He says the effort was worth the reward. Retires <100.
