If you're a new hire at a crypto company or just onboarding to crypto, then you should do these things on Day 1 as a bare minimum to get a good understanding of what its like to do stuff onchain 

1) get an ENS (or Base name) and map it
2) do a swap on Uniswap (ETH / USDC)
3) Lend something via Aave (or Moonwell on Base
4) onboard to multiple L2s and bridge funds between them using relay.link
5) buy/mint any NFT
6) play around with fun apps on L2 (link in next cast)
7)Do all of this on Solana too (apps will be different)
