In Stage I when Pip first encounters Mr. Jaggers on the stairs of Satis House, he is met with an overbearing, burly man who smells of scented soap and has
eyes...set very deep in his head [that] were disagreeably sharp and suspicious.
When he encounters Pip as he descends, the great presence of Mr. Jaggers awes Pip. Jaggers asks him if he is a boy of the neighborhood. Pip replies "Yes, sir." Then, Mr. Jaggers interrogates him about how he comes to be there, ordering him, "Well! Behave yourself!"
In Stage II, Chapter XXIV, after Pip has arrived in London, he is at the office of Mr. Jaggers where he becomes acquainted with Mr. Wemmick and is introduced to the other men in the office. Later, Mr. Wemmick takes Pip to the Old Bailey where criminal cases are heard. There Pip observes Mr. Jaggers, who
...had a woman under examination or cross-examination—I don't know which—and was striking her, and the bench, and everybody with awe. If anybody, of whatsoever degree, said a word that he didn't approve of, he instantly required to have it “taken down.” If anybody wouldn't make an admission, he said, “I'll have it out of you!” and if anybody made an admission, he said, “Now I have got you!” The magistrates shivered under a single bite of his finger. Thieves and thief-takers hung in dread rapture on his words, and shrank when a hair of his eyebrows turned in their direction.
Just as he has intimidated Pip as a child at Satis House and when he has brought Pip news that he has "great expectations," in the courtroom, Mr. Jaggers demonstrates his sharp, detached, and critical personality which is void of any sentimentality. In addition, Jaggers is equally formidable in the courtroom as he is in other settings, barking orders at the witnesses just as he did to young Pip.
