Is Paytm planning to layoff?

Paytm has many openings in product and engineering for at least four to five months. The job posts are even promoted on LinkedIn. However not even a single role is filled and closed. I gave interview for product manager role, received very good feedback, then suddenly after three weeks got a regret mail. Well that is fine but i see all the positions and there at atleast 50 open are not closed for four months. Does any one know what is happening?
