The interview experience was good and fast. Interview feedback was given on the same day in the evening. There were three rounds: two technical and one managerial.

Round 1 was on a Zoom video call with four questions on HackerRank. We were supposed to pass all test cases.

Round 2 was mostly oral.

Round 3 had basic managerial questions.

Coding Round 1

1. Given four arrays: nameOfProducts, priceOfProducts, nameOfProductSold, and sellingPriceOfProduct. Count the products sold at a price different from their purchasing price.

2. Count the number of employees in each department, sorted by count. Also, display 0 if no employees are in a particular department.

3. Make a GET request to a given API and return the processed data.

4. Find the length of the subarray that contains elements with the maximum frequency. For example, given [1, 2, 3, 2, 0, 3], the answer is 3, with the subarray being [2, 3, 2].

Round 2

1. REST vs. SOAP, and when to use each.

2. How to authenticate REST APIs.

3. Explain JWT.

4. NoSQL vs. SQL: when to use each.

5. Encryption algorithms.
