Unity interview questions

My interview process at Unity consisted of a screening call via video with a recruiter then a follow-up video call with the sales manager and a final on-site interview. The on-site experience was mixed overall, I arrived around thirty minutes early for my interview only to be greeted by three individuals sitting at the reception desk. I was casually advised to sign in and then left to my own devices while they carried on chatting.In my opinion, this was unwelcoming and unprofessional, I would have expected to have been offered a drink or at the least somewhere to store my coat/ belongings prior to the interview. I liked all the individuals I spoke with during the interview process and was disappointed when they decided not to move forward with my application. If I could offer any feedback to Unity it would be to provide a more welcoming impression upon arrival to make candidates more comfortable before an interview.
