Harshit Sagar's Review Sourced from Google
What stood out to me about Markup Designs is the people. Everyone I interacted with, from the reception to senior team members, was approachable and professional. There's a real sense of teamwork here, not just a "job" mentality. Great culture.

ASHISH GEORGE's Review Sourced from Google
I had a bad experience with the HR Sneha S. Taken all the round of interviews and later told that my profile was kept on hold. In the JD it was given as immediate joiner. Later after one month the same HR post same opening. By seeing this I mailed HR keeping her seniors. The moment itself she called me back and saying that still my profile is on hold. I don't understand the logic. Earlier I was trying to reach out and she was not picking my call. Would have appreciated if she could have told that the profile is rejected. Same as the organization expecting Professionalism from candidate, they too expect transparency from the organization. In most of the organization HR like Sneha S is a curse.
adharsh .k's Review Sourced from Google
listen up! This old-school interview style is just plain archaic. Seriously, who still tests candidates' memory these days? Wake up and smell the coffee! Technology has evolved light years ahead. We're not in the Stone Age anymore! You don't need to cram every single line of code or concept. What matters is getting the job done with clean, efficient code. Get with the times!
Sumesh T K's Review Sourced from Google
It's been close to a decade with PIT Solutions, and I truly cherished the quality time I spent here. PITS offers a healthy work-life balance, excellent work culture and a politics-free environment. The Management is very supportive and promotes an open door policy. PITS is an idle place for budding talents to learn and grow their skill-set. And for experienced professionals, it's a platform to showcase their skills and broaden their horizons. I would recommend PIT Solutions to anyone without any second thought.
