Maybe. I applied on 05 March, and only just got approved this morning (12 March). There's been a huge upsurge in people talking about Steemit on other platforms due to censorship and de-platforming campaigns (thus how I learned about it), so I think there's been a corresponding influx of applicants.
Not saying you're wrong. Just, there might be other variables at work as well.
Actually, I think it's normal. My other steemit also took about a week. Not bad compared to Poloniex -__-
