The HR / company should mention the company's budget when they call a candidate for an interview because if the company cannot afford a QA candidate with 3 years of experience with a package of 4.5 l pa and above so the candidate will be well aware so that taking a day off for the interview is worth or not. I had an outstanding Technical and HR round but clearly I was out of budget for the company. The company should consider this before calling a candidate who's serving notice period already.
