Need some advice regarding a company

Hey all, hope you're doing well! Just wanted to ask a quick question. So there's this company where I've been interviewing for a job located in banaswadi- Ankercloud Technologies Pvt Ltd Any idea if the company is legit or not? I've checked the website everything seems fine there but when I look at the "office" building, it seems to be built in a residential complex. I've seen even smaller startups open in an office complex. (I'm assumin a company with international clients can do that). So I was just curious if anyone here can help me out with it. Thank you so much!
