Nobody needs a rehearsed elevator pitch for every person they bump into on day one. Something as simple as, “Hi, I’m [name], I just joined the [team/department], nice to meet you,” covers most situations just fine. People appreciate brevity a lot more than a long-winded introduction, especially on a day when they’re likely meeting a dozen new names themselves. The deeper conversation about background and experience is better saved for when it comes up naturally later, rather than being crammed into the first thirty seconds with someone.
