I am a software engineer with ~12 years of experience in backend development. I have worked with various start ups (the likes of PhonePe, Ola) and am currently working at Meta in London. I have been conducting interviews for over 9 years now with a good understanding of expectations from various levels. Having been an early member at PhonePe, I have also had the opportunity to groom very good engineers and can help you with your career as well.
