No Sanskrit absolutely doesn't sound like it did in ancient the ancient times.
Modern (north Indian) Sanskrit pronunciation uses Hindi/Urdu style of pronouncing vowels which was significantly influenced by Arabic and Persian.
Ancient Sanskrit pronunciation was essentially similar to what we call the Prakrit language, which was a more colloquial version and spoken by most people. Bengali, Marathi and Gujarati are a bit closer to that pronunciation, but of course they have changed a fair bit too.
