I'm abreast of angular(2+). I've build several ionic apps, but I've never had an opportunity to build a live angular(web) app. The angular app I built in the past is just a personal dummy app which is not good enough to be included in one's portfolio. I'm going for an angular interview on monday and I need an angular app to show. I'm confident of any question that may be thrown at me. Pls help a fellow.

Are u say saying u need a pure angular project to show, if u are going on monday next week then u have ample time to build an app before then; if u have built with ionic3/angular 6 then replace yr ionic with html/bootstrap call yr apis from a backend and do yr magic.
The fact is ionic is like mobile bootstrap angular 2-6 is same in both aspects of use.
So cook up something before monday check online for angular 2 projects.

Show them d dummy app you created and dont call it DUMMY to them. Say that you've been building up your skill in upcoming/trending web technologies (Rust,flutter,angular etc) and that you are a fast learner and hav got d basics- which is more important- covered. Emphasize your solid skills in other areas e.g ionic. Any good interviewer will hire d candidate that will b best for d company in d long run. If you r good nd can pickup angular quickly,then,you stand a chance. So show them that u are the man they want even though,you dont know angular now. Building a dummy project btwn one week wont cut it cuz u'd still b raw in angular then so shift the focus from angular to ur stronger points,even if they dont hire you,you would hav had d experience of trying to market urself against odds.
