Nalashaa Solutions Ruby On Rails Developer interview questions

Interview process was good and total 4 round (technical, managerial, hr round and offer letter discussion) happens, I cleared all the round and they offered. I accepted the offer but after few days they said that the vacancy has been closed now for ROR, so you can find another job opportunities for ROR, If you will get the job then this offer will be cancel otherwise i will provide other language(other than ROR) to work and that time I was serving the notice period. After the selection I resigned from my company. I was quite unhappy at that time. But later I got 5 offer letter from different company.
