Mphasis NET Fullstack Developer interview questions

The interview was of one round as it was immediate joining process and offer should be released in a single day. I got communication that i am selected and as promised i was hoping to get offer letter on same day and got in call with HR next day for salary discussion. But they never gave me offer. Such a unprofessional and unethical process of interview. Do not recommend wasting time. I gave interview in such short notice and cleared too but after salary discussion and date of joining decision they did not communicate. Such a big disappointment.
