I had bad experience with such a brand name. First of all, i applied backend openings through LinkedIn which suits my interest but never got the call. (even through my referral friend) Suddenly some recruiter agency called me out of blue saying we have opening with Walmart but in Android app. I told him I am interested in server-side work, not app side. he said this has both. but in an interview, Interviewer asked me few basic Android app questions whcih i answer. I also answer Data Structure related questions. but i told him i am not intersted to work on app side. why waste the time of everyone? 1.i dont think the screening process is fair. I have seen agencies tied up with HR in previous companies. 2.after interview, i asked for feedback but no email. luckily i have offers from other 2 product-based companies so i dont care much. But definitely an unpleasant experience.
