Fortunately I never had a leetcode style interview. But I once interviewed at a place a friend worked at and they needed someone to bring their development up to speed (re-architecture, establishing processes, technical lead) and he recommended me for that. The interview partner was their new CTO (joined the company 2 months prior). From the start of the talk he was acting almighty and acted like I should be thankful for the opportunity I have been given. He was asking misleading technical questions. I was super confused first because I assumed malice first ("He is trying to trick me!") but as the interview continued I figured out that he really had no clue what he was taking about. Later during the interview I should describe my experience and I told him about the retail app suite I was the lead dev of for about 2y (POS software + back office + SAP interfaces). He proceeded to tell me that sounds quite nice, but the previous company he worked at did one million transactions per month - hah, eat that stupid peon! I was confused yet again, because that is really tiny? I told him that the project I led did that in a day. He accused me of lying. At that point I politely pointed out that we are not a good fit and wished him the best. 30 mins later my friend called me to ask what happened. The CTO apparently told everyone how poorly I behaved and how measly my skills are. When I told him about what really happened he was quite shocked. He talked to the CEO who did call me next day. I told him a sugarcoated version of what happened. A week later the new CTO was gone. According to my friend he also behaved to other employees in a similar way. The whole story is bizarre.
