Journey
Started as Associate Developer at Nagarro Software Pvt Ltd. Left after 1.5 years for personal aspirations. Joined Techvalens Software Pvt. Ltd., but left after 6 months due to lack of growth opportunities. Searched for new opportunities and received an email for an opening at Lumen Technologies. Contacted sender, went through interviews, and accepted offer.
Application story
I got the mail from the Hr and he arranged the first round of interview which was a technical discussion which went well, and after that I recieved another meeting link for techno-managerial discussion and after this round the final round was HR discussion, after which I got the offer letter from the HR.
Why selected/rejected for the role?
In the interview rounds, I answered almost all the basics questions that were asked to me, In the questions which I don't had any answers, I suggested the interviewer to go through that topic and will get back with the answer which shown my continuous learning attitude, and I solved the problem statement the interviewer addressed in the interview
