Unethical, Unprofessional: Contacted by the manager himself. Had a telephonic and then onsite. Hiring panel consisted of mostly contractors who got converted to full timers. 3 of them asked hard questions which I am sure they themselves couldn't solve. One of them was particularly sounding creepy when he started to ask me questions like how can I access internal APIs of my company from public network and how do we reach service discovery. Walmart's hiring manager reached me back with an offer after two days. I was astounded to know that as part of making a decision on my application, one of the interviewers contacted someone in my immediate team at my current employer to get feedback about me. Their request for feedback went all the way to my director and I got under scrutiny from management. Neither did I give consent for references nor did I give any names to contact. Also, there was no offer made by them by the time they contacted someone for feedback. It was all proactively done by Walmart's team. For this unethical and unprofessional behavior of Walmart's interview team, I decided to reject the offer without negotiation. I informed my manager at current employer that I have rejected the offer. To my surprise, he told me that Walmart communicated that they rejected me :) So here's my advise to you all for interview: 1. If possible, avoid Walmart. 2. Still if you go ahead, avoid disclosing them what you do at your current company. 3. By no means tell them about the team you are working for.
