my problem is how I can write in query builder

Answer 1

You may try something like this. (untested)

$subQuery = DB::table('application')->orderBy('id', 'desc');

$result = DB::table(\DB::raw("({$subQuery->toSql()}) as a"))
    ->mergeBindings($subQuery)
    ->selectRaw("a.*, v.*")
    ->join('vacancy as v', 'a.vancancy_id', 'v.id')
    ->groupBy('a.email')
    ->get();
