Sample Zomato Online Assessment Questions

SDE Role Questions

Question 1: Array Problem

Q: Given an array of delivery times, find the minimum time to deliver all orders (similar to meeting rooms problem).

Problem: Given delivery times for orders, find the minimum time to complete all deliveries with limited delivery agents.

Solution:

public int minDeliveryTime(int[] deliveryTimes, int agents) {
    Arrays.sort(deliveryTimes);
    int[] agentSchedule = new int[agents];

    for (int time : deliveryTimes) {
        int minAgent = 0;
        for (int i = 1; i < agents; i++) {
            if (agentSchedule[i] < agentSchedule[minAgent]) {
                minAgent = i;
            }
        }
        agentSchedule[minAgent] += time;
    }

    int maxTime = 0;
    for (int time : agentSchedule) {
        maxTime = Math.max(maxTime, time);
    }

    return maxTime;
}

Time Complexity: O(n log n + n*k) where k is number of agents

Question 2: Graph Problem

Q: Find the shortest path for delivery (Dijkstra’s algorithm variant).

Solution:

public int shortestDeliveryPath(int[][] graph, int start, int end) {
    int n = graph.length;
    int[] dist = new int[n];
    Arrays.fill(dist, Integer.MAX_VALUE);
    dist[start] = 0;

    PriorityQueue<int[]> pq = new PriorityQueue<>((a, b) -> a[1] - b[1]);
    pq.offer(new int[]{start, 0});

    while (!pq.isEmpty()) {
        int[] curr = pq.poll();
        int node = curr[0], distance = curr[1];

        if (node == end) return distance;
        if (distance > dist[node]) continue;

        for (int i = 0; i < n; i++) {
            if (graph[node][i] > 0) {
                int newDist = distance + graph[node][i];
                if (newDist < dist[i]) {
                    dist[i] = newDist;
                    pq.offer(new int[]{i, newDist});
                }
            }
        }
    }

    return -1; // No path found
}

Product Analyst Role Questions

Question 1: SQL Query

Q: Find the top 5 restaurants by order count in the last 30 days.

Solution:

SELECT
    r.restaurant_id,
    r.restaurant_name,
    COUNT(o.order_id) AS order_count
FROM restaurants r
JOIN orders o ON r.restaurant_id = o.restaurant_id
WHERE o.order_date >= DATE_SUB(CURRENT_DATE, INTERVAL 30 DAY)
GROUP BY r.restaurant_id, r.restaurant_name
ORDER BY order_count DESC
LIMIT 5;

Question 2: Data Analysis

Q: Analyze delivery time trends and identify factors affecting delivery time.

Analysis Approach:

1. Calculate average delivery time by time of day
2. Analyze delivery time by restaurant location
3. Identify peak hours with longer delivery times
4. Correlate delivery time with order value
5. Find restaurants with consistently long delivery times

Key Metrics:

• Average delivery time
• Delivery time by hour
• Delivery time by location
• On-time delivery percentage
