How to deal with this Question? “What is your current CTC?” or “Sorry we can’t give you more than 20% of your Current CTC?

I used this trick, and it worked out. You need to say “since I am underpaid because of so-and-so reason, I don’t want to disclose the current CTC since it is going to affect my expected CTC, which is unfair. I need a so-and-so LPA (do ur research like ambitionbox or glassdoor with respect to ur YoE)”

And the best solution which always works out but a little risky is that you accept the ECTC offer and, before the joining date, interview yourself differently and take that offer to re-negotiate here.

I have used this -

1. If they are adamant on your current ctc as they will give x% more on that, I reject those companies. They don't deserve me
2. I tell them - I am not comfortable sharing my ctc at this point, if you want to know my current ctc to see if you can afford me, let me know the max salary offered for this role and I'll let you know if that's something that works for me

I always say this and it works "I am not comfortable sharing my CTC at this early in the interview process".

Gotta squeeze every rupee they can for rangolis and Domino's parties.

It is fine sharing your CTC while explicitly mentioning that if that is going to be a metric for your Expected CTC then you rather not join. This will result in higher rejections, but the companies that pay in accordance to your skill usually don't ask this in the first place or will be ok in hearing out your range and try to match or come within a reasonable ballpark of it.
