Mastercard interview questions

Me preguntaron sobre mi experiencia laboral, tareas actuales y responsabilidades. También evaluaron cómo resolví problemas en trabajos anteriores, manejo de presión, trabajo en equipo y expectativas a futuro

The technical interviewers started with their introductions. I was expecting one person but they turned out two instead. That's fine but it should have been conveyed by HR in advance. Anyways, two people of their technical team from USA team interviewed me. They started asking a few questions from my resume. What do you know about AWS? how familiar are you with the Ansible? How would you manage the ansible playbooks? How would you validate the outputs of the Ansible playbook scripts? then went into what do you know about API gateways. How do you manage the resiliency in the application or on at the API gateway level? Have you worked in a hybrid cloud environment? What are the tradeoffs of deploying an application to a private cloud vs the public cloud? How does the load balancer work ? How do you know when to scale up and scale down? Asked questions on Application observability? What do you know about NGINX? Where did you used it? How NGINX is used in the API gateways? How would you secure the API gateways, specially from the unknown traffic perspective? How would you handle excessive load on the applications? How is NGINX used in API gateway architecture? How do you know when a system failure occurs ? How would you resolve a support ticket of Severity one? Where would you start from in this case? They asked about API rate limitting etc. How do you know when a load balancer is failing in an air-gapped env? Then, they opened up for my questions that I asked bunch of questions to them: How does the team work ? what proportions of a team member will work on IT support, vs platform engineering, vs application development etc. Where the teams are located.
