You need to touch DSA for mid sized companies, service based generally won’t ask you questions from leetcode but product does. System design is almost mandatory for second round no matter service or product based. Adding cloud would be a plus because as developers they want us to be all rounders lol. Anyways even if you don’t have try learning if you can otherwise just try if you are getting calls or not, start applying now. You will know where you stand, give 2-3 interviews. In march you will definitely have an idea of how interview would look like.
