      We engaged with Cleveroad to develop a custom application that we use to support our customer events. From the beginning, the Cleveroad team worked as true partners to understand our needs and outcomes of the product. They worked in a predictable cadence and were a welcome extension of my team. I would highly recommend Cleveroad to anyone looking trusted software development partner.

      Abhijeet Uniyal's Review Sourced from Google

      Interview process was very good Gave interview for the post of recruitment profile First round went well And, the lady who took my first round of interview was behaving in a very polite and convenient manner The second was with one of the guy who told me about the company's process including it's clients and the services they are offering to the clients And, in the end of the second round, the interviewer gave the feedback in a very positive manner that first time I have talked with you so much as I have never talked with any of the candidates before came for the interview and he really liked my confidence and my way of talking and presenting myself in the interview The third round was with one mam who asked very relevant questions related to my education qualifications and my past experiences so far in my ex organizations And, I also liked the behaviour of the mam who took my last round of interview because the way she was taking my interview in that manner that no one hasn't taken this type of interview before in any of the company This organization is basically a consulting firm And, the good thing about is that they have 5 days working policy If you are applying for the recruiter position in this organization, make sure that you should have relevant experience in that domain and also you should focus on your communication and presentation skills because in interview, they will mostly check your communication skills only and secondly, your experience whatever the work you have done in your past organizations before The nearest metro station to this place is Noida Sector 16 as this place is located very close to the metro station in A block itself
