                          for s in df["Date First Hired"]]

After Change

// one hot encoding to transform them

clean_columns = {

    "Department Name": "one-hot",
    "Assignment Category": "one-hot",
    "Year First Hired": "num"}

// We then choose  which categorical encoding methods to benchmark:
