So - those times are pretty hard, as there are a lot of jobs out there, but there are also a lot of competitors that will also get in your way - so I have to say that it can be very hard and distrubing to know that each company will call to a certain interview more than 100 people and only 1 or maybe 2 persons are going to be selected and actually hired.
Also, there is the problem that those companies do not want to hire people that they consider to be too expensive, or that would become too expensive so this is another problem for all the people that are having great studies at good schools.
So... the work market is pretty disturbed in London and now with this brexit the things ar emore and more complicated - with all those people that are really desperate.
Another complication also consists in the way the jobs are described as you would think that you are going to go to an interview for a travel agency in London for instance but in fact it would be a South London Escort Agency or another dubious company that has posted a fake advert only in order to drive people at their offices for interviews and stuff.
So... you can imagine that I did not liked the ideea of working for this kind of agency, but in the advert it was about a certain agency, the text was pretty professional and so on.
To finally conclude I can really say that life in London can be really hard, but things are probably going to change in better in the near future - at least I am an optimistic person.
