OK, so I have been in the tech industry in the Silicon Valley in the US for over 6 years. I want to move into a different kind of roles which requires some skills and knowledge that I currently do not have/use in my current job. My current job is fairly demanding and I get exhausted when I come back home after working for 10+ hrs. In short I do not get time to prepare myself for the kind of roles I am looking for.
I did interviewed couple of times for the roles I am looking and the feedback from the prospective employer has been on the lines of "that the other candidate had more knowledge from technical standpoint". This has led me to believe that I need to spend some time (like 6-8 weeks or so) in order to bring myself up to speed (The knowledge that I am trying to acquire is well within my reach, it's just that I have not used it in a while).
I have been considering to quit my current job (I am not happy in my current job anyways) so that I lock myself in a room and prepare for the future interviews.
My question(s): I always read/hear that finding a new job is much easier when you have are employed. I would like to understand how would a prospective employer look at this move? Most often recruiters on initial contact will ask what is your work situation. I don't want to look like a somebody who looks suspicious (because he/she is out of work) and with a looser attitude. Will this decision harm more than the benefits that it will bring?
Edit: I can sustain myself financially for over 1 year as I have saved enough.
