I have worked in the same company for last 9 years as an architect and now leaving due to redundancy.
This job was pretty cushy 9-5, no stress, friendly colleagues, flexible work life balance, decent pay etc. Obviously I am coming out of comfort zone. I have interviews coming up in one of the big 4 firm in their technical advisory stream and another in a big industry role both as solution architect in digital space which is interesting and hot. I haven't got these perm roles yet but wondering what should I do if I get them. Having never worked in a consultancy I don't know how working in big 4 feel, would I be able to cope, I am coming 2 level below a partner. The industry role should be familiar territory given my experience.
Consultancies are "ok". I would never call a job at a consultancy "hot" or "interesting" no matter if they described it as programming robotic dinosaurs which destroyed each other with lazers.
They are not for everyone. Though some people tolerate/enjoy them. The consultancy can probably pay you more than what is first offered. Always negotiate hard when getting a job at a consultancy.
I really don't think it is a too massive of decision. That is why there is a probation period. If you don't like the new role, respectfully leave.
