I see this in companies which do recruiting, I really wanted to try, because I long ago wanted to go there to work for this company, but they have no jobs, so now the jobs , how can I miss it, at the interview, I found most of the questions they ask is about SaaS knowledge, I think it may be because knowledge SaaS in this regard now use more of it, so they will ask so much, then I passed the interview, they told me to say yes, now they just need to do SaaS R & D, so just doing this recruitment, which makes me think of my previous knowledge about SaaS really learned useful ah.
