Mass Build Well Livin' Life: Site visit mein kya dekhoon for quality?

Finally fed up of renting and landlord ne phir rent badha diya. Thinking of taking the plunge and buying my own place in Ghaziabad. Have been checking out Mass Build Well Livin' Life. Brochures toh sab sahi lagte hain, but ground reality kya hai? When I go for a site visit, what specific things should I look for to check construction quality in an under-construction project? Like, walls mein already cracks ya finishing issues dikhte hain kya? Ya plumbing/electrical fittings ka rough kaam? And power backup ka kya scene hai wahaan? Is it full flat backup or just common areas? Yaar, don't want to regret later after paying EMIs. Any first-hand experiences ya advice on what to check during site visits would be super helpful.
