Interview preparation tips for other job seekers - If you are thinking to join Tresor then it is good but as from my view it is very disappointing job in my life and I'll never ever serve in this Franchisee (Tresor) in my life again. I've join at think that I will work for Apple but here I faced many problems and at last I have to left the job under the pressure of Area Manager(Varun Mehta). He forced me to do resign or I'll terminate you I work here by giving my best but at last I got nothing only that I get is regrets and unexpected unemployment. HR department is also very careless as if you call for any reason either will not respond to you or will respond after 2-3 days after calling many times over all management is very poor and Ruthless but but in the field of training it is quite better because of (Monish Bhardwaj) Head Trainer of Tresor. He is amazing man with great thoughts and expert knowledge about Apple. I will never join this group nor consider anyone to join this.
