Tekion Software Engineer Interview Questions, Process, and Tips

I participated in a coding challenge that tested JavaScript concepts like currying and object flattening.

• The coding challenge involved implementing a function that demonstrates currying in JavaScript.

• Another part of the challenge required flattening nested objects using recursion.

• I used higher-order functions and closures to achieve currying in the challenge.

• The challenge also tested my understanding of object manipula

Implement tree traversal algorithm to visit each node in a tree structure

• Use depth-first search (DFS) or breadth-first search (BFS) to traverse the tree

• DFS can be implemented using recursion or a stack data structure

• BFS can be implemented using a queue data structure

• Example: Inorder traversal of a binary tree - left, root, right

Find the path in a matrix with the longest sum of elements

• Start from the top-left corner of the matrix

• Move only right or down in the matrix

• Keep track of the sum of elements in each path

• Return the path with the longest sum

An in-memory database is a database that primarily relies on main memory for data storage and retrieval.

• Utilize data structures like hash tables or trees for fast data access

• Implement caching mechanisms to optimize performance

• Consider data persistence strategies for durability

• Support for transactions and concurrency control

• Example: Redis, Memcached

Design a notification service for sending alerts to users.

• Use a scalable messaging system like Kafka or RabbitMQ to handle high volume of notifications.

• Implement a user subscription system to allow users to choose which notifications they want to receive.

• Include different channels for notifications such as email, SMS, and push notifications.

• Consider implementing a scheduling system to send notifications at specific tim...read more

Progress bar in React can be designed using CSS and state management.

• Use CSS to style the progress bar

• Use state management to update the progress value dynamically

• Consider using libraries like react-progress-bar to simplify implementation

In React JS, timers can be implemented using setInterval or setTimeout functions.

• Use setInterval for recurring timers

• Use setTimeout for one-time timers

• Remember to clear the timer using clearInterval or clearTimeout when component unmounts
