As a public company, most projects are won on the basis of Ineco's privileged position upon public agents and governments, both in Spain and abroad. This affects all aspects of the delivered work, from lack of expertise in many disciplines to project quality, which in turn reverts into low client satisfaction.
Ineco's salary inequality is also well known. Plus, as an overloaded organisation chart at high management level, Ineco suffers high overhead costs and it's competitiveness in an open market is quite poor.
For these reasons, whether you are a graduate or a senior, Ineco won't give you the excellence, possibilities to learn and promote that private engineering firms, competing in an open market, will.
Ineco will protect the status quo of part of its organisation by getting rid of the most vulnerable part of it. Under Spanish laws, after two years on a temporary contract, employees' contracts will turn into permanent ones, subsequently making redundancy compensations more expensive. Ineco's common practice is to make the employee redundant right after their first two years in the company, to then hire someone else.
So if you want long term development go somewhere else, where your appreciation overtime counts.
