New Job, Higher Pay, Now I’m Feeling Awkward

I’ve been at my new job for about six months now, and everything’s been going great! I’m getting positive feedback from my manager, and I get along well with the team. The thing is, when I started, my salary offer ended up being much higher than the initial number discussed during my interview. I didn’t negotiate and just accepted the offer. So, fast forward to happy hour with the team, and the topic of salary comes up. I, unfortunately, shared what I’m making, and let’s just say... it didn’t sit well with the others who have been on the team for years and make less than me. They weren’t mad at me, but now I’m feeling a bit uncomfortable and unsure how to handle this situation. Has anyone had something like this happen? How did you deal with it? Let’s chat!

I applied via Referral and was interviewed before Apr 2023. There were 3 interview rounds.

Round 1 - Technical

(2 Questions)

Q1. Gave one problem of binary search?

Ans.

Binary search is a technique used to efficiently locate a target value within a sorted array.

Start by comparing the target value to the middle element of the array.
If the target value is less than the middle element, search the left half of the array.
If the target value is greater than the middle element, search the right half of the array.
Repeat the process until the target value is found or the subarray is empty.

Q2. Built a simple web application to store the data and show it to the browser

Ans.

I would use a combination of HTML, CSS, and JavaScript to create a simple web application that stores and displays data.

Use HTML to create the structure of the web application
Use CSS to style the elements on the page
Use JavaScript to handle user interactions and store/retrieve data
Consider using a backend server (e.g. Node.js) to handle data storage and retrieval
Utilize AJAX to fetch data from the server asynchronously
