Lesson 3.4 · From the past to the present
When you introduce yourself, you almost always say how long you have been doing something: in your role, at your company, in the industry. It is one of the most important things to get right when you meet someone for the first time.

These two mistakes are very common – even at advanced level – and they confuse people when you first meet them.
‘Since’ goes with the start time. ‘For’ goes with the length of time.
We use since + the start time
I have been working at X Company since 2015.
We use for + the length of timenot since
I have been working at X Company for 3 years.
When we are talking about the length of time from the beginning of an event to now, we don’t use the present continuous with ‘for’. This is one of the main mistakes that English learners make when using ‘for’ in business introductions.
✓I have been managing the team for 2 months.
Present perfect continuous with ‘for’ to say how long something has been happening so far
✗I am managing the team for 2 months.
The classic mistake: we don’t use the present continuous with ‘for’ to talk about the time from the beginning until now
‘Be’ and ‘know’ are two key verbs where we don’t use continuous forms. With ‘for’ and ‘since’, we use the present perfect simple – and the same mistake with the present tense still applies.
‘Be’: ✓I have been CFO for 3 years. ✗I am CFO for 3 years.
‘Know’: ✓I have known him for 10 years. ✗I know him for 10 years.
With ‘for’ and ‘since’, these three forms cover almost everything you will say when you introduce yourself.
I have been -ing…
I’ve been leading the sales team since January.
For most activities: working, managing, leading.
I have been at…
I’ve been at the company for 6 years.
With ‘be’: your company, your role, a city.
I have known…
I’ve known Maria since our first meeting.
With ‘know’: people you work with.
In a real introduction, the present simple and the present perfect continuous work together.
What do you do, John?
Present simple to ask about a general, long-term situation
I manage the operations department at X company.
Present simple to talk about a general, long-term situation
I’ve been leading the team for quite a while, about 3 years.
Present perfect continuous with ‘for’ to say how long something has been happening so far
I’m their head of operations for Central Europe.
Present simple to talk about a general, long-term situation
If a continuing event happened in the past and it is now finished, we can use the past simple with ‘for’ and ‘how long’.
Past simpleYou are no longer working there
How long did you work at your previous company?
I worked at X company for 3 years.
Present perfect continuousYou are still working there
How long have you been working at the company?
I have been working at X company for 3 years.
We can also use the present continuous with ‘for’ and ‘how long’ to talk about the total length of time of something. This is often used when talking about how long you are staying somewhere on a business trip.
Present perfect continuousThe time so far
How long have you been staying in the city?
We have been staying here for 3 days.
3 days is the time that you have been staying there so far (you will probably stay for more days)
Present continuousThe total length of time
How long are you staying in the city?
We are staying here for 3 days.
3 days is the total length of time of your stay
We don’t use continuous forms with ‘be’. So for the time so far we use the present perfect, and for the total length of time we use the present simple.
Present perfectwith the verb ‘to be’
How long have you been in the city?
We have been here for 3 days.
3 days is the time that you have been there so far (you will probably be there for more days)
Present simplewith the verb ‘to be’
How long are you in the city?
We are here for 3 days.
3 days is the total length of time of your stay
