Hi everyone, Hope everything is fine. Today I’m going to share my Flipkart Interview experience for the role of UI Engineer I. So without further ado let’s get started.
Online Application: I got referred by one of my colleagues for the position of UI Engineer I.
Round 1(Machine Coding): The interviewer gave me a problem statement that laid out the key points that needs to be solved.
Since the role is for UI Engineer position the requirement was to create a frontend system having below features
Left side of UI
- i) A small form containing radio buttons, 2 text boxes and submit button. The radio buttons needs to be implemented in form of small circles having specific size. The 2 text boxes are labeled as Title and Subtitle
- The background of radio buttons needs to be colored. The colors needs to be randomly generated by calling an API that was given to me.
- The purpose of the form is to act as a filter. It could take input in different form of combinations such as by selecting color, color + inputting title, color + subtitle, color + title + subtitle. Based on the input given, the final output will be filtered accordingly.
- The final output is nothing but a list of rectangular boxes having specific color as background and containing title or subtitle based on filter selected.
- Say if you choose blue color, then all those rectangles having blue color will be displayed.
- Say if you choose green color and input title as “Title1” then all rectangles having color green and title “Title1” will be displayed.
- Say if you choose any filter which doesn’t match with any rectangles then no rectangles will be displayed.
Right side of UI
- The left and right side of UI is to be separated by a thick black line. The features for right side are as below
- i) Another form needs to be implemented containing 2 text boxes, several radio buttons whose background colors is to be fetched by calling the API given to me and a submit button. Again the 2 text boxes are labeled as Title and Subtitle
- Based on the type of input given, a corresponding rectangle will get generated to the left hand side of the UI.
- Say if you choose red color and give title as “Hello” then a rectangle with red background color gets generated with the title “Hello“
Round 2(Coding Round): There were 3 coding questions given. They are as follows:-
- Given a sorted array of N elements and an element K. Find the frequency of element K in the array.
Discussed on edge cases like
- If the element K is not present in the array
- If the array is null or empty
- Given a binary tree, find the maximum path sum. The path may start and end at any node in the tree.
Discussed on edge cases like
- If binary tree is empty or null
- If all nodes in tree contains negative values only.
- Given an array of N elements and an integer X, find 3 elements in the array whose sum is closest to given element X
Discussed on edge cases like
- If input array is empty or null
- If input array contains less than 3 numbers or no such triplet exists in the array
- If there are multiple triplets in the array. (Interviewer confirmed to print any one triplet)
Round 3(UI Tech Round): This round was purely based on UI concepts related to HTML, CSS & JS
Few questions that I could recall are as follows:-
- const word = ‘hello’
word[1] = ‘m’
console.log(word)
- console.log(a)
const a = 1;
There were follow up questions based on var & let
- Currying and hoisting in javascript
- Difference between Typescript & Javascript
- Explain the entire process (what actually happens in backend) starting from sending request from client to server and then back to client.
- <body><script src=”index.js”/><div></div></body>
What will happen to DOM tree if some issue happens in script tag?
- <div class=”blue red”></div> <div class=”red blue”></div>
.blue {background-color: blue;}
.red {background-color: red;}
What will be the background color of both the divs?
- Explain promise chaining in javascript?
- How does javascript figures out that a promise is resolved?
Round 4(Hiring Manager Round): It was totally based on behavioral aspects and Flipkart culture fit. Some of the questions that I could recall are as follows:
- Why you want to join Flipkart? What makes you interested in this job?
- Any role model you want to emulate?
- Discussion on current company project
- How would you ensure that defects are minimized or minimal possible upon release in production?
- What are the different aspects you would look upon when you join a new job?
- What motivates you the most at work?
Thanks. That’s all I could recollect. I hope it would surely help you in preparation for your next coding interview. Till then happy learning and take care.
