Hi @kenan_N_A,
All you need to do is use $match and $group in the following manner:

[
  {
    $match: {
      dept: "DevOps"
    }
  },
  {
    $group: {
      _id: "$dept",
      people: {
        $push: "$name"
      }
    }
  }
]

I hope it helps.

Hi @kenan_N_A,
Oops I missed it, here you go:

[
  {
    $match: {
      dept: "DevOps",
      age: { $gt: 32 }
    }
  },
  {
    $group: {
      _id: "$dept",
      people: {
        $push: "$name"
      }
    }
  }
]

I hope it helps.
