Usually conferences that are overly generic are a scam because anyone's work can fit in this category. Which field of engineering is this conference on? All engineering? This would hardly be an interesting conference to attend for engineers, because it would be very unlikely that someone else publishes in their specific field, on their topic or problem. There are conferences on sub-sub fields of engineering of more than a week in duration and this journal will cover any and all innovations in engineering in 2 days?
A good first start is to ask your supervisor or other professors in your field of study. Since your supervisor's name has to be on the paper alongside yours, they should guide you in this regard.
As a second filter, you should try and publish in a journal or conference that you cited often, or that published on work related to yours, as typically your own work would be a good fit there.
As a third filter, try and find papers that are published at this conference and see if they are any good, and if they all have the same style / formatting. I cant seem to find a template for this conference on their website, which is another red flag. Why would they allow everyone to just post in whatever format they choose?
Something odd, there is a gallery link to a generic gallery website (why would they have this unless it is a general catch all for a bunch of conferences), and none of the photos have any significant number of people in it. In the photos no one is smiling.
Finally, if your paper is accepted in 1 day or in a week, or in two weeks you know no academic or researcher looked at it. A good conference provides peer review feedback, typically of 3 reviewers, sometimes more. A response in a single day, guaranteed fake conference.
Random idea: Maybe we should have rubbish fake papers to submit to conferences before we submit our original work to test if it is a fake conference.
