Uncodemy MERN Stack Course Placement Support Explained

Questions to ask about placement support
[ ] Who reviews my resume and how many times?
[ ] Is portfolio review one-to-one?
[ ] How many mock interviews can I take?
[ ] Are mocks technical (React, Node) or only HR?
[ ] How are interview openings shared?
[ ] Can I repeat a batch if I fall behind?
[ ] What is expected from me to stay eligible?

I am ready for placement support when:
- 3 MERN projects are deployed and working
- Each project has a README with screenshots
- I can explain my code without notes
- I have solved basic JavaScript problems daily
- My LinkedIn matches my resume

// server.js - minimal Express + Mongoose API
const express = require("express");
const mongoose = require("mongoose");

const Task = mongoose.model("Task", new mongoose.Schema({
  title: { type: String, required: true },
  done: { type: Boolean, default: false }
}));

const app = express();
app.use(express.json());

app.get("/api/tasks", async (req, res) => res.json(await Task.find()));
app.post("/api/tasks", async (req, res) =>
  res.status(201).json(await Task.create(req.body)));

mongoose.connect(process.env.MONGO_URI)
  .then(() => app.listen(5000, () => console.log("API on 5000")));

import { useEffect, useState } from "react";

export default function Tasks() {
  const [tasks, setTasks] = useState([]);
  useEffect(() => {
    fetch("/api/tasks").then(r => r.json()).then(setTasks);
  }, []);
  return (
    <ul>
      {tasks.map(t => <li key={t._id}>{t.title}</li>)}
    </ul>
  );
}

// debounce: run fn only after the user stops typing
function debounce(fn, delay) {
  let timer;
  return (...args) => {
    clearTimeout(timer);
    timer = setTimeout(() => fn(...args), delay);
  };
}

const log = debounce(q => console.log("search:", q), 300);
log("re"); log("rea"); log("react"); // prints once: search: react

// Orders per user, highest first (mongosh)
db.orders.aggregate([
  { $group: { _id: "$userId", total: { $sum: 1 } } },
  { $sort: { total: -1 } },
  { $limit: 5 }
])
