I would like to draw the following rectangle divided by two using tikzpicture environment:

However, what I achieved so far is:

MWE:

documentclass{article}



usepackage{tikz}

usetikzlibrary{shapes.multipart}

usetikzlibrary{decorations.text}



begin{document}



% Bend curves from https://tex.stackexchange.com/a/22316/152550

begin{tikzpicture}[delay rect/.style={rectangle split, rectangle split parts=2,draw,

minimum width=1.5cm,minimum height=1cm, 

text width=2cm,align=center,inner ysep=2cm,draw,inner ysep=3mm,inner

xsep=3mm}]  % From https://tex.stackexchange.com/a/452609/152550

    node (start) at (0,0) {Start};

    node (end) at (6,0) {End};

    node[rotate=60,delay rect] (delay) at (3,0) {A1nodepart{two}text here};

    defmyshift#1{scriptsizeraisebox{1ex}}

    draw [->,postaction={decorate,decoration={text along path,text align=center,text={|myshift|hello}}}] (start) to [bend left=10] (delay);

    draw [->,postaction={decorate,decoration={text along path,text align=center,text={|myshift|bye}}}] (delay) to [bend left=10] (end);

end{tikzpicture}



end{document}

Thanks!

to your style definition for delay rec you need to add the option rectangle split horizontal:

documentclass{article}

usepackage{tikz}

usetikzlibrary{shapes.multipart}

usetikzlibrary{decorations.text}

                     rectangle split horizontal,   % <---

                     rectangle split parts=2, draw,

                     minimum height=1cm,

                     align=center,

    draw [->,postaction={decorate,decoration={text along path,text align=center,text={|myshift|hello}}}] (start) to [bend left=10] (delay);

    draw [->,postaction={decorate,decoration={text along path,text align=center,text={|myshift|bye}}}] (delay) to [bend left=10] (end);

end{tikzpicture}

edit:

regarding sub questions in your comment below:

1) reduce the font size of the rectangle (scriptsize)?

in node style definition just define font size with `font=scriptsize`

2) reduce a little more the height of the rectangle?

in height of a rectangles are defined by `minimum height = <desired height>`. you have selected 1cmm, if this is to much, reduce for example to 7mm

3) reduce a little more the width of each part of the rectangle so that there is not so much space between the text and the edges

space between node border lines and nodes content (text) is controlled by `inner sep` (equal for all direction) or `inner ysep` in vertical direction) and `inner xsep` for horizontal. default value is `3pt`. if this is to much to you, than to node's style option add for example `inner sep=2pt`.
