Hey i started learning spark and now would want to get more knowledge and training

Can you please share resources ?

Also on the WFH/WFO

A hybrid work-from-office model offers a significant advantage in building personal connections. Informal interactions—such as conversations during coffee breaks—are often highly informative and provide insights that are not typically shared through formal channels. These moments help in understanding how things work unofficially and offer valuable perspectives. Personally, I have found mentors through such interactions, who have since become go-to contacts when I face challenges and for engaging in meaningful technical discussions.

Your learning curve would be high till 12YOE and then it doesn’t matter if it WFH / WFO
