Company onboarding

When I started to work for my current company I was responsible for the onboarding* of new employees.
The process started on the first work day. There weren’t any prehire activities except for the preparation of a work place and an onboarding program with a schedule.
On day one in the company newcomers filled in and signed all legal papers. After this I met them. We discussed their onboarding programs and went through a preliminary introduction to our company: our intranet and other useful information. After this we went on a tour around the office. Our final destination was the canteen or their workplace.
Onboarding programs used to last around one month and consisted of an orientation program – a presentation about the company, getting to know meetings in various departments and new (hires trainings.?). The specific list of activities and duration of the program varied very much according to the newcomer's position.
The new employee orientation presentation also was conducted by me. Usually there were around twenty new colleagues but once, around one hundred people attended the presentation. We discussed basic information about the company: history, geography, culture – mission statement and values, short term strategy, key policies and compensations and benefits.
It was my final formal meeting with newcomers. Next they were moved to be trained at their workplaces. In this way I have known almost all the company’s employees and to be their first contact and aid was a very nice experience.

*reception?

Very well written! I am not sure about 'onboarding'. Maybe it is a new business management word. I have assumed you meant 'reception'.

Company onboarding

When I started to work in my current company I was responsible for the onboarding of new employees.
The process started on the first day of work. There weren’t any prehire activities except the preparation of a work place and an onboarding program with a schedule and a list of activities.
On  day one in the company newcomers filled out and signed all legally required papers. After the procedures were finished I met them. We discussed their onboarding process and went through the first intro about the company: our intranet and basic resources of useful information. After this we went on a tour around the office. Our final destination was a canteen or their work spaces.
Onboarding programs used to last around one month and consist of a new employee orientation program – a presentation about the company, getting to know meetings in various departments and new hire training. The actual list of activities and duration of the program differed greatly depending on the position of a newcomer.
The new employee orientation presentation also was conducted by me. Usually there were around twenty of our new colleagues but once the presentation occurred we were visited by around one hundred people. We discussed basic information about the company: history, geography, culture – mission and values, a strategy for near future, key policies and compensations and benefits.
It was my final formal meeting with newcomers, next they move to be trained in their work spaces. Through this process  I have known almost all of the company’s employees and to be their first meeting and helping person was a very nice experience.
