实习选组求建议

最近实习team match填survey，hr给了几个选项让排序，小白在这方面没什么经验，想问问地里大神的意见。
1. cloud & data platform - manage cloud resources, design and develop distributed systems and workflow, work on concerns of the cloud like monitoring and shared libraries. tech stack主要是python，go，c，shell，docker
2. IoT - implement backend API's and microservices for data processing and real-time analytics, build scalable systems on the cloud platform, apply machine learning algorithms to solve problems related to Predictive Maintenance of IoT devices, tech stack 主要是python，Scala，go， java，docker, Kubernetes
3. performance engineering - implement performance benchmark, contribute to and maintain internal tools, tech stack主要是python，go，java，docker，tensorflow，redis，ansible。我本人对1和2更感兴趣，但是对于1有点concern，因为我是转专业的system方面比较弱，怕要补的东西太多一下子做不来。
劳烦各位大神从工作前景和发展的角度帮忙分析推荐一下啦！谢谢！谢谢！

132吧，个人建议
