HR will promise work life balance and all sorts of perks.
They will promise good mentorship and professional advancement.
The truth is that once you are installed the work will get piled on your desk and you will be coerced to take on more work, even if you are unprepared or under-qualified. You will be in a position where you will not be able to say 'no' to work, even if that work is beyond your level of preparation.
Support? None. The senior guys that are already entrenched in senior positions will be nothing but a hindrance to your work. They are accountable to no-one.
HR is no to be trusted. When I came to them with these issues, and the insane overtime I was working all I was told was: 'that's the nature of your position', after I was recruited under the pretense that I would have a good work life balance.
Further, as a low level employee, seniors will not respect your schedule or self autonomy. Seniors will demand that you take on authoritative and forceful relationship to sub-trades, which in my case I knew would lead to burning my good reputation with guys that I had been working with for years.
Lastly, I am not rating this company at the lowest '1-star' because it would not be fair - the opportunities are there, but only for those who are willing to work 12-hour days and abandon family, friends and all sense of a healthy balanced life.
Don't mess up like I did, do not trust their HR.
I would even say that this is a sophisticated company that spends a lot in marketing itself to potential employees. Even some of the other glassdoor reviews seem entirely skewed.
Oh yeah, BONUS: this company strongly encourages some sort of cult adoration of Geoff Smith, the son of the actual founder of EllisDon, who apparently inherited the company and is now the boss (he doesn't care at all about employees).
That's why EllisDon has the highest revolving door and lowest retention of professionals among the larger construction management companies in Canada.
