After reading many reviews in Glassdoor, I realise every company is a bad company. Apparently, unhappy staff took to Glassdoor to voice their unhappiness against the company. Every company will surely have unhappy staff due to misfit or personality clashes with bosses or colleagues. So I suggest you can read reviews in Glassdoor, but don’t be too overly influenced by all the negative reviews. My father works whole life in DSTA btw. Of course he has his fair share of ups and downs, but he is well compensated for all his hard works.
