Hey, I was planning to pursue master's in computer science mostly in 2022 , but there's a problem, after tons of research I came to know the universities(mostly Canadian) I am planning to apply requires a supervisor to get the admit (Also confirmed this by contacting already studying students from my country through LinkedIn and yocket.) Now the thing is in these 4 years of my bachelor's in computer science, I never learnt a new trending technology nor it was included in my curriculum like ML , CLOUD ETC ETC.(I belong to a not so famous Indian University).I just know HTML,CSS,JS,REACT and few designing tools ( not a graphic designer) but I want to pursue master's in ML , HCI OR Networking (had networking in my curriculum but it was way outdated. ). How should I approach a supervisor provided I have 0 experience in the above listed tech and research in them OR in general 0 experience in research.
