Mayer Brown interview questions

Super straightforward interview conducted on-site for a Hybrid role. I tried to keep it professional, but the LPA interviewing was very unprofessional and rude. The LPA and the secretarial manager interviewing me were very hostile from the very beginning and made it clear that they were only interviewing me because the Director of Administration had been impressed with my resume and interview. From the very beginning the LPA treated me with contempt (due to my prior diverse legal experience) even going as far as asking me "if I had proper childcare" because they may need me to stay after hours - which is not only inappropriate, but legally questionable due to its discriminatory nature under employment laws. I'm pretty sure that question was not HR-approved. Extremely shady, condescending, and uncomfortable on-site interview experience that I withdrew my candidacy. If this is how they treat the interviewees, imagine how they treat employees!
