I came across the position on LinkedIn and applied through their career website.

Initially, I received an email from the Development Manager asking me to complete an assignment, which had a week-long deadline. After submitting the assignment, I received an invitation for an online technical interview, scheduled for one hour. The interview began with an introduction, followed by in-depth technical questions. The interviewer presented a DSA problem, which I solved quickly.

A few days later, I received another invitation for a 1.5-hour technical interview, this time with two interviewers. They reviewed the take-home assignment I submitted and asked numerous questions regarding the project, including how I would optimize it. Then, they asked questions about Java, Spring Boot, and REST APIs, along with some design-related queries. They also gave me another DSA problem, which was of medium difficulty. After taking a few hints, I was able to solve it.

Four days later, I received a call from HR offering me the job.

The assignment was to build a "CO2 emission calculator."
