How to sort in mongodb v3.6

Question

I'm having issues placing the last added item in a list of object/items appear at the top. Basically its like a job board and i want the latest jobs appear at the top and not the bottom. I've tried using Post.find({}).sort({ date: -1}).exec(function (err, posts) {... }); but it doesn't seem to be working or maybe i'm not implementing it correctly, i'm still quite new to this.

 // Example code, but similar to actual code //models config let jobSchema = new mongoose.Schema({ title: String, category: String, description: String, type: String, url: String, email: String, apply: String, location: String, company: String, path: String, created: {type: Date, default: Date.now} }) let Job = mongoose.model('job', jobSchema); // {type: String, default: "placeholdeimage.jpg"} //routes config var storage = multer.diskStorage({ destination: function (req, file, cb) { cb(null, './public/uploads/'); }, filename: function (req, file, cb) { var originalname = file.originalname; var extension = originalname.split("."); filename = Date.now() + '.' + extension[extension.length-1]; cb(null, filename); } }); app.get('/', (req, res) =>{ res.redirect('/jobs') }) app.get('/jobs', (req, res) =>{ Job.find({}).sort({ date: -1}).find(function(err, jobs){ if(err){ console.log('error') } return res.render('index', {jobs: jobs}) }) }) //add form route app.get('/jobs/add', (req, res) => { res.render('add') }) app.post('/jobs', multer({storage: storage, dest: './public/uploads/'}).single('file'), (req, res) => { req.body.description = req.sanitize(req.body.description); Job.create( (err, addJob) =>{ if(req.file){ let fullPath = "uploads/"+req.file.filename; let document = { title: req.body.title, category: req.body.category, description: req.body.description, type: req.body.type, url: req.body.url, email: req.body.email, apply: req.body.apply, location: req.body.location, company: req.body.company, path: fullPath }; let job = new Job(document); job.save() }else{ console.log('file not uploaded') logo = 'noimage.jpg' } //redirect to index page return res.redirect('/jobs') }) }) app.get('/jobs/:id', (req, res) => { Job.findById(req.params.id, (err, jobDetails) => { if(err){ res.redirect('/jobs') }else{ res.render('details', {job: jobDetails}); } }) }) app.listen(port, process.env.PORT, process.env.IP, ()=> console.log(`Server is running on ${port}`)) 

 <!--writen in EJS--> <div class="container"> <% for (const job of jobs) { %> <div class="row"> <div class="column logo" style="width:10%;"> <img src='<%= job.path %>'> </div> <div class="column title"> <h2> <%=job.title%> </h2> <p> <%=job.company%> </p> </div> <div class="column type"> <h2> <%=job.type%> </h2> </div> <div class="column location"> <h2> <%=job.location%> </h2> </div> <div class="column"> <h2><a href="/jobs/<%= job._id %>"><button>Apply</button></a></h2> </div> </div> <hr> <% } %> </div>

Sorting in MongoDB is done like so:

db.Post.find({ MATCHING CRITERIA }).sort({ date: 1 })

where 1 is ascending and -1 is descending.
