ProficientNow interview questions

I recently completed a single-round interview at a company, where I was assigned a task. Everything went smoothly and the team appreciated my work, and in the final round, the MD himself expressed confidence in my skills, assuring me I'd receive an offer in a few days. Two weeks passed with barely any communication, and today HR informed me the role was given to someone willing to join at a lower salary. I had turned down another offer based on their assurance, and now I’m left without a job. An unfortunate consequence of a process that lacked transparency and professionalism!
